Kérastase Genesis Anti-Hair Fall Nourishing & Fortifying Hair Serum for Weakened Hair 30ml

Kérastase Genesis Anti-Hair Fall Nourishing & Fortifying Hair Serum for Weakened Hair is a daily leave-in treatment designed for hair that’s prone to falling due to breakage. The lightweight, jelly-like serum is enriched with Aminexil, Edelweiss native cells and ginger root to help support the scalp and the look of fragile lengths. With regular use, it helps to reinforce the feel of the hair fibre, promote the appearance of fuller, thicker-looking hair and leave strands feeling smoother and more resilient from root to tip.

Ideal for weakened hair of all types, this serum fits easily into an existing haircare routine. Simply apply to the scalp on dry or towel-dried hair, either in the morning or before bed, and leave in without rinsing. The formula works alongside your usual Genesis shampoo and conditioner to help minimise the feel of hair fall due to breakage, while maintaining a comfortable, cared-for scalp and a healthier-looking finish day after day.

How to use
How to Use:
Start with clean, dry or towel-dried hair. Apply 3–4 pipettes (or drops) of Kérastase Genesis Anti-Hair Fall Nourishing & Fortifying Hair Serum directly onto the scalp, working section by section. Gently massage the serum into the scalp with fingertips to distribute evenly. Do not rinse and style hair as usual.

Frequency:
Use once daily, in the morning or before going to bed, following the guidance on the product information.

Application Technique:
Focus application on the scalp rather than the lengths, parting the hair to expose small sections and applying the serum close to the roots. Allow the lightweight texture to absorb before brushing or styling.

Best Practices:
Apply after shampooing and towel-drying when using as part of a full Genesis routine. Use consistently over several weeks for best cosmetic results. Avoid over-applying to lengths to keep hair feeling light. Store the product closed and away from direct heat or sunlight.

Safety Tips:
For external use only. Avoid contact with eyes; if this occurs, rinse immediately and thoroughly with water. Discontinue use if irritation occurs and follow any additional instructions on the packaging. Keep out of reach of children.
