Brilliant and smells expensive

This stuff is a keratin+silk smoothing and softening 'renewal' spray that can be used wet or dry. On wet hair, you can actually feel the difference in softness when it is still wet, and it is a NOTICEABLE difference. Pretty impressive! After spraying on my comb slipped right through the tangles and after blow drying my hair was really soft, smooth and manageable. This might be all you need, depending on your hair type, as a pre-blowout product. When I've put this on wet and let my hair air-dry, I have also noticed an increase of shine.

My hair has never felt better

I cant say enough good things about this product. My hair has never felt this good, since using it. My hair is so soft, and smells so so good. If you have dry or brittle hair, or even want to tame frizz, or just use to keep your hair healthy.... try it out! Its BY FAR the best spray to use on your hair after you wash it. 100% recommend.

Best Product for Dry Hair

Searched on the market for every kind of leave in conditioner for my frayed hair. I have highlights and straighten it every day. This product is by far the best. It leaves my hair feeling smooth and silky. I used to use It's A 10 Miracle Leave in product and it was okay and went through the bottle in less than a month. The Keratin Dose is a larger size and costs much less. I have used this for 2 years now and my hairdresser even notices the difference. So if you have dried, damaged and bleached hair go for it.
