“Absolutely love this product. Have been using it for about 7 years now. I originally bought a 120ml bottle and still have some in it. Tho in saying that I did buy a 60ml bottle about 2 years ago for travelling and have used about 1/2 of that one as well. So I may have used about 140ml all up in 7 years. I use it after I have straightened my hair....which on average is about every 4 - 5 days. You only need a tiny bit. I put it mainly on the ends and then wipe what is left on my hands on the top of my head then give my hair a brush. Works a treat to keep the wispy bits down. I use about 1/5 of a teaspoon. You only need a really small bit.”
