After 5 years of research and trying out new recipes I finally got a shampoo bar my hair seems to be really happy with.
Individual hair seems to have very different needs, that is why I made small tester bars - try those first, when you're not sure whether these might work for your hair.
You won't even need an extra conditioner with these bars, it's basically build in. I really noticed a big difference.
I do rinse my hair with (rosemary infused) organic apple cider vinegar after washing (roughly 2 TBSP vinegar to about 1l Water). That helps to brings the pH of the hair and scalp back to its preferred acidic range, supporting a healthy acid mantle and bacterial flora.
Soap scented with a essential oils: Orange 5fold, Rosemary
Saponified oils of (Coconut, NZ Rape Seed, Castor, Cacao butter). Rosemary infused apple cider vinegar, SCI*, Glycerine, Essential oil, citric acid, Vegetable Silicone**
*SCI = Sodium Cocoyl Isethionate (SCI) Powder
"Sodium cocoyl isethionate is a coconut oil-based surfactant. It is very mild on skin, hair and eyes and has a silky skin feel. SCI makes a great lather and is good for making liquid shampoos and shampoo bars. .... -Based on fatty acids from natural, renewable coconut oil.... -Biodegradable....
Our SCI powder is very fine which can be irritating. We recommend using a dusk mask when handling."
(quoted from my supplier's webpage: https://zenaroma.co.nz/product/sodium-cocoyl-isethionate-sci-powder)
And boy - don't I know what damage that powder can do.... I made the mistake of adding it to my soap without wearing a mask - and felt it immediately rising into my sinuses - I was sick for solid 3 weeks, headache, sinuses hurt, coughing - it was awful. When I'm using it now, I'll wear hubby's dust mask! Never again. But it's really nice for your hair. Believe me, that I would never touch it again otherwise.
This is derived from olive oil, acts like a hair conditioner and "improves hair brightness and smoothness (easier combing), like silicones"
