first of all I'm new here and hopes to find a lot of information on many hair issues.
I'm not greying yet, but I have light blonde, reddish hair and would like to have it darker. Of course, I dyed and hennaed it many times before but now I've heard that applying castor oil could darken new hair growth. Has anyone experienced that? But there are so many brands and types of castor oil on the market that I just don't know which one is the best for hair darkening?
I've just bought hesh castor oil, but I don't know whether it's something good or not.
Could anyone help me? Many thanks
