OUAI Hair Thickening Spray - Thickening & Volumizing Spray for Instantly Thicker, Fuller-Looking Hair - Protects, Strengthens & Repairs with Amaranth Peptide & Amino Acids (6 Fl Oz)

I like this thickening spray. I’ve used this a few times. I have straight, fine hair. After washing my hair I sprayed this from roots to ends. My hair felt thicker and no tackiness after I blew dried my hair. The first time I used this I over sprayed the top of my hair and it looked a bit greasy. So my suggestion is you don’t need to use a lot of the product. It also has a nice subtle scent.

Seems nice, not sure how well it actually thickens but I like it

Makes a lot of difference in my fine hair.

Really good

I'm really happy with how my hair looks after using this thickening hair spray. I just give my hair a mist of this after towel drying my hair, and blow dry, and my hair has more body and fullness. It's much easier to style! I haven't noticed any hair growth yet, but the condition of my hair has improved, so I'd recommend it!

I used Ouai’s previous volume spray and I loved it. Unfortunately, they stopped making it. I’m not happy with this current product. It offers no shine, no hold and leaves my hair feeling dry. It does offer some volume. I expected more from this company and for the price.

Makes your hair feel like it’s loaded with hair spray but it does look a lot fuller. Don’t like the way my hair feels after using it. You might as well load your hair down with hair spray

My hair is going through a shedding phase at the moment and I wanted to restore some of the volume. This spray is supposed to help your hair look more volumous and I was impressed that it indeed made my thin hair look fuller. I sprayed some on my freshly washed hair and then blow dried it. I think it made my hair feel a bit sticky, as though I had used hair spray but it did help with the volume. The spray has a pleasant yet subtle scent.
