Does your hair feel more fragile than it used to? Are you noticing broken strands in your brush, thinner-looking ends, or difficulty keeping the length you want?

At DanielShay’s Salon Boutique Spa, we believe beautiful hair starts with understanding what your hair needs. That’s why we describe Kérastase as prescriptive haircare: identify the concern, then choose a routine designed to address it.

For weakened hair prone to breakage, the Kérastase Genesis system brings together cleansing, conditioning, targeted scalp care, and heat protection. It offers a complete approach that can be tailored to different hair types.

Stronger Hair Starts With Understanding Breakage

When hair seems unable to grow past a certain length, growth may be only part of the story. Breakage can cause you to lose length at the ends even while new hair continues to grow at the roots.

Genesis is designed to help reduce hair fall due to breakage from brushing. By protecting fragile strands, it may help you retain more of the length you’re growing.

That distinction matters: Genesis is a strengthening haircare system, not a treatment proven to restart hair growth or reverse medical hair loss. If you’re experiencing sudden or persistent shedding from the roots, a dermatologist can help identify the cause.

The Shampoos: Choose the Right Foundation

Genesis offers two shampoos, allowing your stylist to match your cleansing routine to your hair’s needs.

Bain Hydra-Fortifiant is designed for fine or oily hair. It cleanses while providing fortifying care, making it an option for clients who want strength without an overly rich shampoo.

Bain Nutri-Fortifiant is the richer option for thick or dry hair. It provides moisture and helps with detangling while caring for weakened strands.

Choosing between them is part of the prescriptive approach. Two people may both struggle with breakage but need different levels of nourishment.

The Conditioner: Fondant Renforçateur

Genesis Fondant Renforçateur is a lightweight, fortifying conditioner that helps strengthen weakened hair while adding nourishment and shine.

It is a useful step for hair that needs softness and manageability without the richness of a heavier treatment. Easier detangling also makes it simpler to handle fragile hair gently.

Your DanielShay’s stylist can help you determine how much to use and where to apply it, especially if your roots tend to flatten while your ends need conditioning.

The Mask: Masque Reconstituant

When your hair needs more intensive conditioning, Genesis Masque Reconstituant provides a richer treatment for weakened strands prone to breakage from brushing.

Kérastase recommends it as a weekly treatment. It can take the place of your regular conditioner on treatment days, giving your routine an extra level of nourishment when needed.

You don’t necessarily need both conditioner and mask at every wash. The right balance depends on your hair’s texture, condition, and how easily it becomes weighed down.

The Daily Serum: Sérum Fortifiant

Genesis Sérum Fortifiant is the daily scalp-care step in the collection. Unlike a finishing serum applied mainly to the ends, this lightweight, non-greasy formula is applied directly to the scalp.

Kérastase positions it as a fortifying treatment that helps strengthen hair and reduce breakage when used as part of the Genesis routine. Apply it to dry or towel-dried hair, gently massage it in, and leave it in without rinsing, following the directions on your bottle.

Consistency makes this step part of your everyday haircare habit, rather than something you use only after shampooing.

The Thermal Protectant: Défense Thermique

Strengthening your hair also means protecting it during styling.

Genesis Défense Thermique is a lightweight leave-in heat-protecting spray that helps strengthen weakened hair, manage frizz, and protect against heat up to 450°F, according to Kérastase. Apply it as directed before heat styling.

That protection rating isn’t a recommendation to turn your tools to their highest setting. Your stylist can help you choose a temperature appropriate for your hair.

Can Different Hair Types Use Genesis?

Genesis can suit a range of hair types when breakage is the concern. The different shampoos and conditioning options make it possible to adjust the routine for finer hair, richer moisture needs, and different styling habits.

But prescriptive haircare means choosing what fits—not assuming everyone needs the same collection. Your main concern may be breakage, dryness, color damage, frizz, or loss of fullness, and your stylist can help you decide where Genesis belongs in your routine.
