Aveda technology to fortify hair

Yes, I recommend this

I used this product a few years ago and have only just started to use it again. Does not affect hairstyle or make it goopy. Dries down and hopefully over time will help strengthen my hair.

Not for me

Originally posted on aveda.co.uk

Unfortunately the leave in treatment did not work well for me. I followed the instructions and prepped everything and the product made my hair feel very heavy and oily. It kinda had a stickiness to it too. I'm an Aveda customer already and I think I'll stick to the Damage Remedy that I'm using.
