Keratin
It gives back the protein the hair has been losing and controls frizz. It leaves the hair manageable and shiny, and doesn't leave it poker straight: the curl softens, it doesn't disappear.
Hair treatments
Not all straightening treatments are the same, nor do they suit every type of hair.
What each treatment does
Nanoplasty
A longer-lasting straightening with a sleeker finish than keratin, with formaldehyde-free formulas. It needs hair in good condition to take well, which is why sometimes it has to be reconstructed first.
Hair “Botox”
It doesn't straighten and has nothing to do with Botox, despite the name: it fills in and adds body to hair that's fine, dull or damaged. It works best when the problem is a lack of apparent density.
Hydration
For hair dried out by sun, salt or the hairdryer. You'll notice it from the very first session but it lasts less than a reconstruction: it's maintenance, not repair.
Reconstruction
When the fibre is truly damaged —repeated bleaching, daily straightening— the first thing to do is reconstruct. Skipping this step is what stops a straightening treatment from holding.
Care at home
We'll recommend the shampoo and/or mask your hair needs to keep it in the best condition.
