What Is Kérastase Densifique?
Densifique is Kérastase's range built specifically for hair that's thinning or losing density - not damaged hair, not dry hair, but hair that's simply becoming finer over time. The hero ingredient is Stemoxydine, paired with a concentrate that's designed to be massaged into the scalp daily. It's not a miracle cure, and we won't tell you it is - but it's one of the few ranges we've seen genuinely change how hair looks and feels over a few months of consistent use.
Who Actually Needs This Range?
If you're noticing your ponytail feels thinner than it used to, more scalp is showing through at the part, or your hair just feels 'weaker' than a few years ago, this is the range to look at. It's not aimed at people with thick hair looking for volume - it'sspecifically for hair that's genuinely thinning, whether that's from age, hormones, stress, or just genetics.

How Long Until You See Results?
Honestly - this isn't an overnight fix. Most of our clients start noticing a difference in thickness and how full their hair feels after around 6 to 8 weeks of consistent use, with the scalp concentrate applied daily. Skipping days here and there will slow things down, so it's worth building it into your morning or evening routine like you would a skincare step.
How We Use It In-Salon (and What We Recommend for Home)
In the salon, we'll often pair the Densifique shampoo and masque with the daily scalp concentrate for the best results - the shampoo and masque do the conditioning work, while the concentrate is where the real active ingredients get to work directly on the scalp. If you're just starting out and want to try one product first, the concentrate is the one to prioritise.
Frequently Asked Questions
Is Kérastase Densifique good for fine hair or thinning hair?
Both, really - it's designed for hair that's losing density, which often shows up as fine, flat-feeling hair. If your hair has always been fine, it'll still help; if it used to be thicker and has changed, that's exactly what it's built for.
How often should I use Densifique products?
The scalp concentrate is designed for daily use. The shampoo and masque can be used as part of your normal wash routine, 2-3 times a week.
Can men use Kérastase Densifique?
Yes - the range isn't gendered, and we recommend it to plenty of male clients dealing with thinning at the crown or temples.
Is Densifique suitable for coloured hair?
Yes, it's colour-safe. If colour protection is your main priority alongside thinning, we're happy to talk through pairing it with a colour-care shampoo.
