My hair cannot live without this stuff. Does your hair stick straight out when you hold the tips? It won’t after this! Your hair will cascade down like a waterfall. I recently ran out and notice a huge difference. So expensive but worth every cent.

Somehow made my hair greasier. My hair is thin & gets oily & frizzy easily, this did not help what so ever
