As someone with thin, fine hair, I can tell you good shampoos are few and far between.
Like yes, all shampoos claim to ‘cleanse’ your hair, but if you don’t use the right kind of shampoo, it can actually leave your hair feeling dirtier than before you washed it.
Seriously, I've lost count of the number of times I’ve washed and dried my hair only to have a mini melt-down because it looked flatter and greasier than before.
If this is sounding familiar, good news: I’ve finally figured out what was wrong.
Turns out my hair doesn't have a personal vendetta against me. I was just using the wrong shampoo for fine hair. Allow me to explain...
Wait, What’s the Deal With Fine Hair and Shampoos?
Alright, so fine hair tends to get real greasy, real fast.
This means we have to wash our hair a lot more often than other hair types to avoid looking like, well, Gollum.
But washing your hair isn't always enough to keep fine hair from looking flat and slicked.
Some shampoos are packed with silicone and heavily-moisturising ingredients... which is fine if you’ve got thick, luscious locks. Love that for you. But for us fine-haired peeps, loads of heavy moisturising ingredients can weigh our locks down, resulting in hair that looks and feels flatter than an IKEA flat pack.
Bonus points: Using the wrong shampoo for fine hair can leave you with those rats tail-like greasy clumps of hair at the back. You know the ones.
For all of the reasons listed above, I’ve been on the hunt for a GOOD shampoo that: cleanses fine hair, is gentle enough to allow for frequent washes, helps strengthen to avoid split ends and breakage, and also leaves hair feeling voluminous and fab AF.
And guys, I think I’ve found The One. Just quietly, things have gotten pretty serious.
Let me introduce you to the Kérastase Genesis Bain Hydra-Fortifiant Shampoo for Thin Hair.

My Review of Kérastase Genesis Bain Hydra-Fortifiant Shampoo for Thin Hair.
So, you’ve probably already realised I
really like this Kérastase shampoo for my fine hair. But here's why
Kerastase Genesis Fortifying Shampoo for Thin Hair 250ml is now the best shampoo for fine hair in my eyes.
Firstly, can we take a moment to appreciate the beautiful packaging of the Kerastase Genesis shampoo ? The transparent pink container tells you everything you need to know without even opening the product. It’s a lightweight shampoo, which is exactly what we're after.

This shampoo has a gel-like texture - if you have fine hair, you want to steer clear of anything too creamy or opaque because it generally means the formula will be heavy on the moisturising ingredients.
The hydrating formula of the Kerastase anti hair fall shampoo cleanses without drying, which is really important because fine hair is prone to breakage and split ends. And when you have to wash your hair frequently, it’s important that the shampoo doesn’t strip your hair too hard.
Before using this shampoo, my hair would get greasy about 0.03 seconds after stepping out of the shower. I couldn’t figure out why and it was just really disheartening when I already had serious hair concerns. (You can read my article on my experiences with
female patterned baldness here.)
But this shampoo has 100 per cent made me feel like I finally understand my hair. It wasn’t my hair that was wrong, it was the shampoo I was using! I mean, would you look at this fresh, voluminous hair?! That OOMPF.

The product also lathers up real good and you only need a tiny amount, which means it lasts for a long time. But nobody is perfect. The scent can be a little over the top. But that’s kind of a Kérastase thing. They love big, bold, floral fragrances. Just be prepared to feel like you’re showering under a field of flowers.
Now I’ve found a good shampoo designed for my hair type and hair concerns, it’s made a huge difference to my hair health, my mental health and my water bill. It can’t get better than that!
The Kérastase Genesis Range.
Even though the shampoo is my favourite child, Genesis is actually a whole new dual anti hair-fall haircare range inclusing the Kerastase genesis shampoo and conditioner. It has some pretty impressive stats behind it, including:
Reduces intense periods of hair-fall in 6 weeks^.
84% less hair-fall due to breakage*.
Boosted hair fibre retention and strength.
The
Genesis range includes shampoos for both thin and thick hair, a conditioner, masque, heat protectant, hair serum and treatment ampules.
The Kérastase Genesis Fortifying Anti Hairfall Serum has become super popular recently, we even had Beauty IQ writer Neha Prasad do a whole
review on it here, that's how much she loved it!
And here are some glowing Kerastase Genesis fortifiant hair serum reviews from Adore Beauty customers:
"I'm actually obsessed with the serum! I apply it every night then go in with my scalp massager and massage it through. It has helped my hair fall tremendously over the months." - Kiki.
"I absolutely love this product, I've noticed I have very little hairfall now, and some new baby hairs. It is expensive but it's worth it." - Ruby.
"Cannot live without this product! Makes my hair feel so thick and smells amazing." - Lex.
But for me, the other two stand out products from the range you’ll find in my bathroom are:
The perfect Kerastase Genesis set!
