! You do not need to use alot! I normally use a small amount (2 drops) onto my hands and work it through my hair after I have dried it some. Don't use too much or you will look oily! It takes away all the frizzy and leaves it healthy, smooth, soft and shiny looking. It smells amazing and has heat protection.I have thick wavy hair that does not like to be straight! This is a staple for my blowout or straightening routine! A bottle of it usually lasts me about 6 months.
