Is this for thin hair?

My hair is fine and thin and it definitely helps my hair look fuller.

What are the ingredients?

Aqua (Purified Water), Ethanol, Cetrimonium Chloride, PEG-12 Dimethicone, Hydrolyzed Soy Protein, Syzygium Luehmanii (Lillypilly) Extract, Oenothera Biennis (Evening Primrose) Oil*, Aloe Barbadensis (Vera) Leaf Extract*, Urtica Dioica (Nettle) Extract*, Camellia Sinensis (Green Tea) Leaf Extract*, Olea Europaea (Olive) Leaf Extract*, Phenoxyethanol, Polysorbate-20, Hydrolyzed Wheat Protein, PEG-40 Hydrogenated Castor Oil, Polyquaternium-7, Ethylhexyl Methoxycinnimate, Parfum (Fragrance), Citric Acid. *Certified Organic

Can I use this on hair that has keritan or brazilan blowout?

I don’t see why not. I think it’s a great volumizer. I find it does nothing to smooth frizz (which is not what it’s intended for) I use a separate paste after drying my hair to smooth out frizz and tame fly aways. The paste is called Original Mineral K-Gravel texture clay. I don’t think is available on amazon. I think I bought it on google. Hope that helps you make a decision!
