PDP Section FAQs
FREQUENTLY ASKED QUESTIONS
How often should I use Genesis Serum Fortifiant?
For best results in strengthening weakened hair, we recommend using the Kerastase Fortifiant anti-hair loss serum daily for 6 weeks.
Can I use the Kérastase Genesis Serum on wet hair?
We recommend using the Genesis Serum Fortifiant Hair Serum on a dry or towel-dried scalp, section by section. Do not rinse.
Will Genesis Serum Fortifiant Hair Serum weigh my hair down or leave a residue?
No, the Genesis Serum Fortifiant Hair Serum is a lightweight formula that will not leave a residue when hair dries. It works to strengthen hair while leaving a lightweight, non-greasy finish.
Should Serum Fortifiant Hair Serum be applied to the hair or scalp?
Serum Fortifiant Hair Serum should be applied to the scalp to strengthen hair and prevent hair fall due to breakage from brushing. Apply to parts of the scalp where your hair needs the most strength and in areas where you notice less density.
How much Genesis Serum should I use?
We recommend using three to four pipettes of serum on dry or towel-dried hair.
Do Anti-Hair Fall Serums Work?
Yes, an anti-hair fall serum can be highly effective when used consistently. These formulas are enriched with active ingredients that strengthen hair at the roots, minimise breakage, and support scalp health. With regular application, the anti-hair fall serum helps improve hair density and retention over time.
Which Serum Is Best for Hairfall?
The best hair serum to reduce hair fall is one that not only strengthens weak strands but also nourishes the scalp. A high-performance hair fall control serum targets thinning areas, while an anti-hair loss serum works to re-anchor hair follicles and prevent premature shedding.

Rich scalp moisturizer without the greasinessI find it to be a great product. I have probably half the hair left since the hairfall started almost 13 years ago. I have used multiple products including minoxidil but no real benefit in either arresting the hairfall OR regrowing them. Over the last few years, I have been using these "serums" and at least the hairfall has been arrested OR reduced to a point. Genesis is the latest product I have started using and the overall experience has been very good - it certainly moisturizes the scalp without making it greasy, spreads and absorbs quickly and so far no further hairfall.

Great Product!!The product is really good . It reduced my hairfall in a month.
The problem is the bottle finishes off fast in a matter of 2 weeks time if the recommended dosage of 4 pippettes is used daily. The second problem is that it is too expensive for a bottle that finishes off in two weeks.
