I have fine but thick coloured hair and use this product because I love my irons. The description says for curly hair but it smooths my hair out brilliantly. I think I've used every heat protection spray/cream on the market & I always come back to this one. It does not make hair greasy or leave build up. It has a delicate smell & makes hair feel soft. A little goes a long way which makes it good value for money, my current tube has lasted 6 months. I use it every other day on towel dried hair before styling with hair dryer & irons.
