Review on 🌿 Formaldehyde-Free Keratin Hair Treatment: INVERTO ONE Hair Botox - Instant Results, Professional Brazilian Keratin Blowout by Anna Green

Revainrating 5 out of 5

I love other Keratin Research products but not this one.

I have ordered this 3 times because I was so convinced I was doing something wrong. I've always had great success with Keratin Research products and have recommended them to others for years, but this 'reliable' formula leaves my hair acidic and only lasts 7-8 washes max. I love that this product is formaldehyde free and it stings my eyes like the original product. It's surprisingly easy to use, but I'm not sure it's worth doing every month or two, and it's definitely not worth the weird smell it causes in my hair. I would still highly recommend other Keratin Research products but not this one.

Pros
  • New to my collection
Cons
  • Clarity
