Hair loss & alopecia

Hair loss and alopecia.

Hair loss takes many forms — seasonal shedding, androgenetic alopecia, alopecia areata, telogen effluvium and more. Each pattern needs its own assessment.

Clinical hair loss & regeneration treatments

What treatment can I use for my hair loss?Hair loss doesn’t have a single cause — seasonal shedding, androgenetic alopecia, stress and nutrition all behave differently. The right treatment starts with a proper diagnosis at the scalp and follicle level, not a random product.Read more What technique or treatment is there for alopecia areata?Alopecia areata is a non-scarring, immune-related condition that appears as round or oval patches. There’s no single treatment that works for everyone — options depend on extent, duration and the individual case.Read more

Scalp & daily habits

Scalp care and daily habits.

Greasy roots, dryness, sensitivity, itching and build-up are often influenced by daily habits — washing frequency, choice of shampoo, technique and rinsing.

Seborrheic control & scalp biobalance

Can stress cause an itchy scalp?Stress may intensify itching, increase the urge to scratch and aggravate an already sensitive scalp. Learn how to interrupt the itch–scratch cycle and when persistent symptoms need professional assessment.Read more Are specific shampoos recommended for greasy hair?Greasy hair is the result of excess sebum on the scalp, not a problem of the fibre itself. Specific oily-scalp shampoos — alternating between complementary formulas — help control oil without being aggressive.Read more Is it advisable to wash your hair every day?It depends on your scalp type — greasy, normal, dry or sensitive — and your lifestyle, more than on a universal rule. The key is suitable products and a gentle technique whenever you wash.Read more

Dandruff

Dandruff, dry or greasy.

Dandruff has two main forms — dry and greasy — both linked to disturbances in the balance between sebum, scalp microbiome and skin renewal.

Clinical dandruff & microbiome care

What is dandruff and why does it occur?A visible, excessive shedding of cells from the outer scalp. It can be dry (small white flakes) or greasy (larger, adherent yellowish scales), often linked to sebum, microbiome and individual sensitivity.Read more

Hair fibre & styling

Hair fibre and styling.

Colour, heat, fixatives and mechanical handling have a cumulative effect on how the fibre looks and how long it stays in good condition.

Bio-repair, moisture & fibre restructuring

Do dyes change the nature of hair?Most permanent dyes aren’t neutral — they alter the cuticle and cortex to deposit colour, and repeated use can cause dryness, roughness, loss of shine and breakage. A patch test before each new dye is essential.Read more Is the use of the dryer, foam and gel harmful?Not automatically — the issue is overuse and poor technique. Very high heat, foam or gel on the scalp, and incomplete rinsing all contribute to damage over time. Moderation and proper cleansing keep them compatible with healthy hair.Read more

General hair care

General hair care.

Hair health is also about everyday habits, diet and scalp care — and knowing what really makes a difference over time.

Does cutting your hair often make it grow faster?No — hair grows from the follicle, not from the cut end. Trimming doesn’t change growth rate or natural strength, but it does help remove split ends and reduce breakage over time.Read more To what extent can food affect or benefit the hair?A lot. Hair is one of the first markers of imbalance in the body — protein, iron, zinc, B vitamins, vitamin D and essential fatty acids all play a role in normal growth.Read more How can you have healthier hair?Healthy hair starts with a healthy scalp. Gentle washing for your scalp type, careful handling of heat and chemicals, a balanced diet and good sleep and stress habits all support condition over time.Read more
