- Asked by Hanna

If you have colored treated hair, I would highly recommend this leave in spray. It performed very well on my hair in our humid climate in Houston Tx.

The directions say to spray in damp hair, so I did. My hair was damp and I sprayed from root to tip. I then blow dried my hair. My hair felt so greasy and I didn't like that!!
