Next Generation Keratin treatment - 18.0oz - For coarse hair.

I have extremely thick wavy hair and have been using various products to help ease the process of smoothing my hair for over 15 years. My hair stylist introduced me to this product a few years ago. He charged $200 for one treatment. I bought my first bottle here on Amazon in June 2017 and just ran out in March 2020. Glad to see I can still find it here on Amazon. While it has odor, it's not as strong as many others. Plus, I love that I only have to go one day before I can put my hair up in a pony tail or wash. Very happy with this product!

A great product , but can make you feel nauseous and lightheaded It definitely smokes and can sting your eyes and give you a headache

Been using this for years. No fumes, can blow dry with bounce, color pops and drying time cut in half . Worth the price.

Destroyed my hair...the stylist highlighted then colored my very fine hair then applied the product for coarse hair. My hair was totally destroyed! Burned, frayed and whole strands breaking and falling out.

Works great but made my eyes burn. How is this possible if there are no harmful chemicals in it.

This is an awesome product and customer service was great! It shipped very fast! I love forever smooth! It's the best thing I have done for my hair. Dries in half of the time and it is very smooth. Never frizzy even during humid summer days!

The product is excellent! We use at the salon all the time, and with rave reviews! Came very quickly too!

Great product
