Thank you for that shampoo recipe. I sometime get eczema on my scalp, and will try it next time.
I noticed that you said that the use of the coconut oil was optional. I will tell you my experience with coconut oil and hair growth.
My daughter, too a scissors to her hair when she was three years old, cutting some of the hair down close to the roots, so she had a lot of patches. I treid a number of things and the hair growth was very slow.
One day I came across extra virgin cold press coconut oil, and I started using this on her hair. The regrowth was so rapid that I only noticed that her hair was even length,, when i went to wash it one day. I continued putting the coconut oil on her hair, and now her is thick, strong, shiny and soft. I now believe in coconut oil for grooming the hair.
