For finer hair, I needed to dilute it.
It's a little thick. I have fine hair and divided it into half and thinned it with water. I use it as a moisturizing spray before drying with the diffuser and also to refresh on non-wash days. For thicker hair types I'm sure it would be fine as is. The sprayer on the bottle is very nice - comes out as a fine mist. Very nice product.
