I am continually on a quest to find the perfect, most natural as possible products I can find and in the past this has led me to attempt to make my own shampoos. Those attempts have so far been fruitless as I ended up with a product that left a dullness to my hair that I could not live with, a kind of residue despite rinsing with cider vinegar in the water, although I haven't attempted this yet with my own soap which I make myself at home.
Now I make all my own 'products' and treatments with only natural ingredients. I use various Indian herbs to make a traditional paste which cleanses and conditions and my dry frizzy hair has been turned right around. I began using this in February 2005 after much research and deliberation, and four months later I can confirm that I have not used any synthetic products in all that time and can honestly say I don't think I ever will again unless I have to.
I also use fresh Aloe Vera from my own nice big plant (he's lovely, his name is Oliver *grin*) and apricot kernel oil or jojoba oil.
For those who don't like the idea of herbs only washing I will include some reviews and suggestions:
avalon organic botanicals mint thyme shampoo and conditioner
I tried the lavender version in the range which was good but not as moisturising as the mint thyme variety. This conditioner doesn't contain silicones so there is no buildup. The shampoo doesn't contain SLS and is therefore less harsh than many other shampoos. it worked well for a while, and even the Conditioner worked well for a while as a conditioner only wash, but I must admit I grew tired of it after a while due to dullness and irritable scalp.
