The French brand can be found in salons and showers around the world, loved for its science-backed, targeted approach to hair concerns and ability to make every day a good hair day.
As beauty editors, we got curious. We could see (and feel!) a difference in our hair after using just one product, but would a full Kérastase routine make a difference to our overall hair health?
To test this, we invited Kérastase’s education team to examine the strands and scalps of seven MECCA team members using the innovative K-Scan smart camera. After their consultation each person was prescribed a bespoke Kérastase regimen tailored to their hair type, concerns and goals. Then, began a four-month process, where our team used only Kérastase products to the bottom of the bottle.
Two of our team members, Tisha and Georgia, were focused on defining and hydrating their thick, curly hair. After adhering to their personalised routines for several months, they came back for their second K-Scan with Kérastase educator Lesley Fourna. Here are the results…

Hair Type: Thick and curly
Initial Concern: Maintaining texture and curl pattern
Hair Goal: Improve moisture and curl definition
Tisha’s Routine:
- Curl Manifesto Shampoo
- Curl Manifesto Conditioner
- Curl Manifesto Crème de Jour Anti-Frizz Cream
- Genesis Serum
- Curl Manifesto Curl Refreshing Spray
- Curl Manifesto Hydrating Nutrition Mask
There was a collective gasp when Tisha, and her longer, even more luscious curls, stepped back onto set. She says although she noticed the growth, she was shocked by how visible the difference was when comparing the images (and she’d had a haircut between shoots!).

The K-Scan revealed that the difference could be seen at a scalp level too. Before starting her Kérastase routine, Tisha’s K-Scan results showed a ‘high risk’ for hair fall (meaning individual strands were likely to fall out faster than new ones grew). After a few months of using her personalised regimen, which included a serum specifically designed to strengthen and anchor hair at the root, the K-Scan recorded a ‘low risk’ for hair fall.

According to Georgia, this routine line-up has been a game-changer – making it much easier to manage and maintain her thicker texture: “My curls have become visibly tighter and more defined, but my hair doesn’t feel like it’s being weighed down by a tonne of product.”

Seeing the before and after results with the K-Scan affirmed Georgia’s belief that her hair had become so much healthier: “Knowing I’m using products selected for my specific hair concerns and goals has not only transformed my hair but, most importantly, it’s increased my own confidence in looking after it!”
