Hair fall is an increasingly common hair concern tied closely to our lifestyles, diets, mindsets and rituals. For two at MECCA HQ, Jamine and Mackenzie, it became the focus of a four-month journey aimed at strengthening their strands – part of a larger group of seven MECCA team members who were curious to see if using only Kérastase products could improve overall hair health and help them reach their goals.
The process began with a detailed scalp scan by Kérastase’s education team using the high-tech K-Scan smart camera. From there, Jamine and Mackenzie followed bespoke routines tailored to their individual concerns - no other products allowed!
After several months of consistent use (and empty bottles), they returned for a second round of scans to see the results. Here’s what happened...

Jamine, Brand Marketing Lead
Hair Type: Thin and straight
Initial Concern: Hair fall
Hair Goal: Improve hair strength, minimise hair fall and stimulate growth.
Jamine's Routine:
- Genesis Fortifying Shampoo for Thin Hair
- Genesis Reconstructing Anti-Hairfall Conditioner
- Genesis Intense Fortifying Treatment
- Genesis Anti-fall Fortifying Serum
- Genesis Reconstructing Anti-Hairfall Hair Mask
- Elixir Ultime
Boosting strength and encouraging growth were high on Jamine’s priority list and following her first K-Scan she was ready to tackle hair fall from root to tip with the Genesis range by her side.
Designed to help anchor hair into the scalp and reinforce the fibre, this collection stimulates hair growth by creating the best possible environment for new hair to grow.
Jamine’s risk of hair fall had dropped significantly, from a high-risk score of 67% before starting her Kérastase routine to a low-risk score of 35%.
What’s more, her hair diameter diversity score increased from 36% to 79%. According to Leslie, this indicates an increase in the amount of ‘new growth’ coming through. Leslie also notes that the ‘new growth’ was especially concentrated at the top of Jamine’s head (right where the Brand Marketing Lead had been focusing her serum application), pointing out the number of smaller, finer hairs emerging in that area.

Using this as a teaching moment, Leslie stresses the importance of applying treatments and serums – like the Genesis Intense Fortifying Treatment and Anti-fall Fortifying Serum Jamine used – across the entire scalp, not just the crown, to support more even results.
“I didn’t think I could grow so much hair in such a short period of time!” Jamine tells us. As for the next phase of her hair journey, she’ll continue using her favourite product, the Genesis Shampoo, to promote even more growth, while also maintaining hydration and shine.

Mackenzie, Brand Marketing Manager
Hair Type: Fine and straight
Initial Concern: Lack of volume
Hair Goal: Improve hair strength and minimise hair fall
Mackenzie’s Routine:
- Densifique Bodifying Shampoo
- Densifique Bodifying Conditioner
- Densifique Bodifying Scalp Treatment
- Spécifique Potentialiste Balancing Scalp Serum
- Blond Absolu Heat Protecting Cicaplasm Primer
- Blond Absolu Cicanuit Night Hair Serum
“I’ve never had so many comments on my hair as I have had in the last few months,” Mackenzie declares as she sits down for her second K-Scan. “My friends and family keep saying my hair is looking so much thicker and longer, so something is definitely working!”
While Mackenzie’s hair goals were similar to Jamine’s, she was prescribed a lineup featuring the Densifique range during her initial consult. While both collections support hair fall, Densifique is specifically designed for fine strands, helping strengthen, plump and create density at the roots for hair that appears thicker.

And strengthen it did. After four months of using the range, Mackenzie’s risk for hair fall decreased from a high-risk score of 75% to a low-risk score of 27% said Leslie, as she pointed out the visible new growth across Mackenzie’s scalp.

When accepting her award for one of the best hair transformations, Mackenzie thanked her favourite products in the range, the Densifique Bodifying Shampoo and Bodifying Conditioner: “From the first wash, I immediately felt that my hair was denser and more ‘plumped up’ post-hair dry... I’ve also noticed that it holds its shape much better after styling, which is a relief because my hair has often struggled to hold a curl!”
