Anagen
The anagen phase is the active growth phase. During this time, the lash is formed in the hair follicle and is continuously supplied with nutrients. Only a portion of all lashes are in this phase at the same time.
LASH HEALTH
Healthy natural lashes start with understanding.
Lash Health explains how natural lashes are structured, what influences them and why professional application, suitable care and eye health belong together.
Basics
What does Lash Health mean?
Natural lashes are much more than an aesthetic feature. They are part of the eyes' natural protective system and help keep dust, small foreign particles and other environmental influences away from the surface of the eye.
Lash Health describes the biological and structural condition of natural lashes and their immediate surroundings. This includes an intact hair fiber, a healthy hair follicle, a physiological growth cycle and a well-groomed eyelid edge.
Lash Health does not start with a single product or treatment. What is crucial is the interaction between anatomy, lash cycle, eye health, professional application and individually tailored care.
anatomy
The natural lash is a small, specialized terminal hair with an important protective function for the surface of the eye.
Each natural lash is anatomically a terminal hair. The visible hair shaft merges into the root, which is anchored within the hair follicle in the edge of the eyelid. At the lower end is the bulb with the dermal papilla, which is supplied by fine blood vessels and plays a central role in the natural growth cycle.
The hair fiber is essentially determined by the cuticle and cortex. While the cuticle acts as an outer protective layer, the cortex gives the lash shape, stability and elasticity. Lashes differ significantly from hair on the head: they grow in a different biological rhythm, fulfill an important protective function for the eyes and are sensitive to friction, inappropriate care and chemical or mechanical stress.
This anatomy is of central importance for professional lash treatments. Lash lift, tinting or lash extensions do not affect just any hair fiber, but rather a specialized hair in the immediate vicinity of the edge of the eyelid and the surface of the eye. A professional assessment therefore always views hair structure, hair follicles, eyelid edges and eye health as an interconnected biological system.
Lash cycle
Lashes grow in phases - not all at the same time.
Natural lashes do not grow continuously, but rather go through a biological growth cycle with four successive phases. Because each lash is at a different time in this cycle, not all lashes grow at the same time. This natural principle explains why an average of one to five natural lashes fall out per day and are replaced by new ones.
Catagen
The catagen phase marks the transition between growth and rest. Active growth ends and the hair follicle prepares for the next phase of the natural cycle.
Telogen
During the telogen phase, the lash remains anchored in the hair follicle but stops growing. At the same time, the next lash is already developing.
Exogenous
In the exogenous phase, the natural lash finally falls out. This process is part of the normal biological renewal process and is not an indication of damage. A new growth cycle then begins for the same hair follicle.
Understanding this biological cycle forms the basis of every professional lash treatment. Since individual lashes are always in different growth phases, the results of a lash lift or lash extension change continuously and grow in accordance with the natural lash cycle.
Eye Health
Lash Health starts at the edge of the eyelid.
The health of natural lashes does not start at the hair fiber, but at the edge of the eyelid. This is where the lashes grow from the hair follicle, this is where the meibomian glands are located and this is where the tear film forms the first protective layer on the surface of the eye. Eye Health and Lash Health are therefore closely linked.
Palpebra (eyelid)
The eyelid protects the sensitive surface of the eye and distributes the tear film evenly over the eye with every blink. At the same time, it forms the anatomical basis for the edge of the eyelid, lashes and meibomian glands.
Margo palpebralis (lid edge)
The edge of the eyelid is the transition area between the skin and the surface of the eye. This is where the natural lashes grow from their hair follicles, and this is also where the meibomian glands open. A healthy eyelid edge forms the basis for eye health and Lash Health. Inflammation of the edge of the eyelid (blepharitis), severe irritation or active infections should be clarified professionally or medically before cosmetic treatments.
Glandulae tarsales (Meibomian glands)
The meibomian glands produce lipids that stabilize the outer layer of the tear film. This reduces the evaporation of tears and protects the surface of the eye. If the meibomian glands do not function adequately, the tear film can become unstable. Dry or irritated eyes can therefore affect both eye health and professional lash treatments.
Filmum lacrimale & Folliculus pili
The tear film protects the surface of the eye from drying out, while each natural lash is formed, anchored and nourished during its growth in the hair follicle. Together they form the biological basis of healthy natural lashes.
The health of natural lashes is not determined solely by the hair fiber. Only the interaction of the edge of the eyelid, meibomian glands, tear film and hair follicles creates the biological conditions for long-term healthy natural lashes. A healthy eyelid edge, a stable tear film and well-functioning meibomian glands form the basis for long-term healthy natural lashes. Persistent irritation, pain, crust formation or unusual loss of lashes should be checked by a specialist or ophthalmologist.
Influencing factors
What influences Lash Health?
The health of natural lashes is not determined by a single factor. Biological conditions, mechanical stress, chemical processes as well as care and hygiene all influence the condition of the hair fiber and the eye area.
biology
Genetics, age, hormonal changes, nutrition, general health and the individual growth cycle determine the length, density, thickness and speed of regeneration of natural lashes.
Mechanical stress
Frequent rubbing of the eyes, improper make-up removal, chronic tensile stress, unsuitable extensions or their improper removal can put unnecessary strain on the hair fiber and hair follicles.
Chemical processes
Chemical treatments such as lash lift or tinting are generally compatible with healthy natural lashes if indicated correctly and carried out professionally. What is crucial is a careful lash analysis, suitable products, correct exposure times and controlled implementation.
Care
Regular cleaning of the eyelid edge, suitable care products and coordinated aftercare support a clean environment for natural lashes. At the same time, gentle treatment of the hair fiber helps to avoid unnecessary mechanical stress.
hygiene
Both hygienic work processes in the studio and a consistent daily home routine help to keep the eyelid edges and natural lashes clean and reduce unnecessary stress.
Individual assessment
Before each treatment, lash thickness, density, elasticity, growth phase, eyelid edge, eye health and possible contraindications should be assessed individually.
Lash Health is not caused by a single factor. Only the interaction of biological requirements, a healthy eyelid edge, a physiological lash cycle, professionally carried out treatments and suitable care creates the basis for long-term healthy natural lashes.
Professional treatments
Professional treatments and natural lashes
Professional lash treatments change the appearance of natural lashes in different ways. For Lash Health, the treatment itself is less important than its professional implementation. Careful analysis, suitable products and controlled processes contribute significantly to keeping natural lashes healthy in the long term.
Lash lifting / lash lamination
A professional lash lift or lash lamination changes the shape of the natural lash through a controlled chemical reshaping of the hair structure. What is crucial for Lash Health is not just the treatment itself, but above all the quality of the products used, a careful lash analysis, correctly coordinated exposure times and a controlled implementation. Using tested, professional brand products with clearly defined treatment protocols helps achieve reproducible results and reduces the risk of overtreatment. If carried out professionally, suitable product selection and correctly coordinated exposure times, a professional lash lift is generally compatible with healthy natural lashes. However, like any chemical treatment in the eye area, it is not completely risk-free and requires careful analysis and attention to possible contraindications.
Lash extensions
With lash extensions, the natural lash is supplemented with an artificial lash. The decisive factors for Lash Health are a weight that matches the natural lash, precise insulation, suitable adhesives and gentle removal of the extensions. Extensions that are too heavy, inadequate insulation or improper removal can put unnecessary strain on your natural lashes. Professionally carried out treatments differ significantly from long-term, overloading applications.
Tinting
Colouring natural lashes primarily improves optical definition. Since the treatment takes place directly in the sensitive eye area, careful product selection, consideration of possible allergies and professional application are particularly important. If there is existing irritation, active inflammation or known hypersensitivity, treatment should be postponed.
Professional treatments and Lash Health are not in contradiction to each other. What is crucial is an individual assessment, controlled treatment protocols, high-quality products and responsible implementation by appropriately trained Lash Artists.
Ingredients
Which ingredients support the lash fiber?
Many ingredients can condition, smooth or make lashes appear more supple. This is not the same as medically proven growth. That's why we differentiate between fiber care, appearance and real promise of growth.
| ingredient | function | Scientific classification |
|---|---|---|
| Ceramides | Support the hair barrier and help retain moisture in the hair fiber. | Plausible to indirect evidence to support the hair fiber and its barrier properties. |
| Panthenol | Improves suppleness and moisture retention of the hair fiber. | Well proven for conditioning and cosmetic hair care. |
| Hyaluronic | Binds moisture and supports the elasticity of the hair fiber. | Plausible evidence for moisture and suppleness. |
| Hydrolyzed collagen | Film-forming protein building block to care for the hair surface. | Supports the hair fiber cosmetically, but no proven growth effect. |
| Hydrolyzed oats | Vegetable proteins for surface care and conditioning. | Plausible support of the hair fiber. |
| Hydrolyzed Keratin / Keravis™ PE | Protein and peptide systems for temporarily strengthening the hair fiber. | Hydrolyzed keratin has plausible evidence for temporary conditioning of the hair fiber. Keravis™ PE is based on manufacturer and formulation-specific data; Permanent biological repair of the hair structure has not been scientifically proven. |
| lanolin | Nourishes the hair surface and reduces moisture loss. | Classic conditioning ingredient. |
| Glycerin | Humectant to improve suppleness. | Well established in cosmetic hair care. |
| Peptides | Supports the appearance and condition of the hair fiber. | Promises of growth are only scientifically proven to a limited extent. |
| Bimatoprost* | Medical active ingredient to extend the growth phase. | The currently best-studied medical ingredient for real lash growth. Bimatoprost requires a prescription and is not a component of cosmetic lash lift or care products. |
Many cosmetic ingredients can nourish, condition or make natural lashes appear more supple. However, this must be clearly distinguished from medically proven lash growth. For Lash Health, both the quality of a formulation and a realistic scientific classification of its effect are crucial. Cosmetic care and medically proven lash growth should be clearly distinguished from one another.
Myth or fact?
Science instead of beauty myths
There are many statements circulating about natural lashes, lash lifting, extensions and care. A clear fact check helps to create realistic expectations and classify Lash Health technically.
| myth | fact |
|---|---|
| Lash lifting damages natural lashes. | Not fundamentally. Product quality, lash analysis, correctly coordinated exposure time and professional implementation are crucial. |
| Extensions destroy natural lashes. | Not automatically. Weight, insulation, adhesive, hygiene and gentle removal determine the strain on the natural lash. |
| Keratin permanently repairs lashes. | Keratin and proteins can provide cosmetic care and conditioning. Permanent biological repair of the hair structure has not been proven. |
| All lash serums promote growth. | Many serums primarily improve care and appearance. Real growth effects have mainly been proven for medical active ingredients. |
| Waterproof mascara is fundamentally harmful. | The decisive factor is usually the greater mechanical stress during removal and not the mascara itself. |
| Any lash loss is a problem. | The daily loss of individual lashes is part of the normal growth cycle. Noticeable gaps, pain, crusts or persistent irritation should be clarified. |
| Castor oil makes lashes grow faster. | There is no reliable clinical evidence to support faster lash growth with castor oil. |
| Cutting lashes makes them thicker. | Cutting does not change hair follicles or lash density. A shortened lash can appear duller, but this does not mean it will grow back any thicker. |
| A Patch Test guarantees safety. | A Patch Test can help to identify possible reactions at an early stage. However, it is not a complete security guarantee. |
Lash Health is created through the interaction of biological conditions, suitable products, professional treatments and consistent care. This interaction forms the basis for long-term healthy natural lashes.
FAQ
Frequently asked questions about Lash Health
What does Lash Health mean?
Lash Health describes the condition of the natural lashes and the surrounding eye area - including hair structure, lash cycle, eyelid edge, meibomian glands, tear film and professional care.
How many lashes do you lose per day?
On average, a person loses around one to five natural lashes per day. Since each lash is in a different growth phase, lost lashes are continually replaced by new ones. Only if there is unusually severe lash loss or visible gaps should it be clarified professionally or medically.
Can an lash lift damage natural lashes?
Not fundamentally. What is crucial is a careful lash analysis, tested professional products, correctly coordinated exposure times and professional implementation.
Do lash extensions damage your natural lashes?
Not automatically. Weight, precise insulation, suitable adhesives and gentle removal are crucial for the stress on the natural lash.
Which ingredients support natural lashes?
Ingredients such as ceramides, panthenol, hydrolysed collagen, hydrolysed keratin, Keravis™ PE, glycerin or hyaluronic acid can support the care, suppleness and moisture retention of the natural lash.
Do lash serums really make lashes grow?
Many cosmetic serums primarily improve skin care and appearance. The strongest evidence for real lash growth is with medical ingredients such as bimatoprost.
Why is the eyelid edge so important?
At the edge of the eyelid there are hair follicles, meibomian glands and the transition to the surface of the eye. A well-groomed eyelid edge therefore supports eye health and Lash Health.
Why don't all lashes grow at the same time?
Each lash goes through its own cycle of anagen, catagen, telogen and exogen phases. This is why natural lashes are never all in the same growth phase at the same time. This means that the results of a professional lash lift or lash extension grow evenly and typically remain visible for around six to eight weeks.
What can I do myself for healthy lashes?
Gentle cleaning of the edge of the eyelid, little mechanical stress, appropriate aftercare and high-quality professional treatments help to keep natural lashes healthy in the long term.
When should I postpone treatment?
If there is acute eye irritation, inflammation, pain, unusual lash loss or visible changes in the eye area, the cause should be clarified first.
