Kérastase Genesis Anti Hair-Fall Fortifying Serum 90ml

Kérastase Genesis Serum 90ml: choose your scalp step

Kérastase Genesis serum is a leave-in scalp product for weakened hair prone to breakage. This SMC Traders listing is for the 90ml Anti Hair-Fall Fortifying Serum. Choose it when you want a scalp step in your routine, rather than a shampoo or an oil for the lengths.

Before you buy: compare the full product name and bottle size. Genesis products have different jobs, even when their packaging looks similar. A smaller bottle, a wash product and this serum are separate purchases.

Is this the Genesis product you need?

• For a leave-in scalp step: this listing is the serum. You keep it on after application.
• For cleansing: the Genesis Bain Hydra-Fortifiant shampoo 250ml is a separate rinse-out product. A serum does not replace washing.
• For choosing a routine: start with the job you need a product to do. You do not have to buy every item in a range to make a considered choice.

Kérastase describes the serum as helping reduce hair fall associated with breakage. That is a cosmetic claim about fragile hair; this page does not promise new hair growth or treatment of a medical cause of hair loss. Read that distinction before comparing it with products that make different claims.

How to use Kérastase Genesis serum

Check the directions on the bottle you receive first. The current UK directions say to use it once a day for six weeks. Apply three to four measured pipette doses to a dry or towel-dried scalp. Fill each dose to the pipette mark, work in sections, and leave the product in. Avoid your eyes; rinse them thoroughly straight away if contact occurs.

Choose a time you can keep consistent, such as after your morning routine. Keep the bottle's instructions handy rather than guessing an amount from the size of a dropper. If your packaging gives different directions, use those instructions and contact us if you need clarification before use.

Ingredients and suitability: check before ordering

The current UK manufacturer's ingredient list includes alcohol denat. and fragrance. If you avoid particular ingredients, compare the complete printed list with your requirements. Ingredient names highlighted in advertising are not a substitute for that check.

Formulas and packaging can change. Ask us for a current bottle or box photograph if a particular ingredient, label detail or direction affects your buying decision. We should confirm that detail from the actual item rather than assume it from another Genesis product.
