Amazing - I am a customer for life

Hands down - the best hair product I have ever used. It truly makes your hair shine in a healthy way. I have seni-wavy/curly hair and it enhances and softens my curls. Plus it also makes the undertones in my hair pop out. Truly amazing product I see myself buying for the rest of my life.

Recommended along with all keratin smooth products

I use the entire Tresemme Keratin Smooth line to do my own blowouts at home. This product, alongside the other keratin smooth products, does an amazing job. It has a lovely, subtle scent that lasts. The straightening and heat protection it provides is wonderful! I have extremely thick and coarse hair, so any product that does this well gets a high recommendation from me. I actually recommend all of the keratin smooth products from the shampoo to the spray.
