Baking soda is alkaline (pH ~8 ) so damaging to both skin (pH ~5.5) and hair (pH ~4.5), you can reset the pH with dilute vinegar but you cannot replenish the skin's protective acid mantle.
Read beauty blogs written by people with a science background, there is an awful lot of rubbish written on the interwebs. Natural Haven, Swiftcraftymonkey, Beauty Brains, Bare Faced Truth are all decent. Also some great articles here on NC by 'curl chemist' Tonya McKay, she says about alkaline soaps
"Another very important ingredient to avoid for long, curly hair especially is soaps. In the past, I have written an article cautioning users of soap to be careful, but basically concluding that it was probably okay to use soaps with an acidic rinse and lots of moisturizing agents. Based on the following information obtained from the research of Dr. Ali Syed (a hair care researcher who specializes in African and curly hair), I cannot in good conscience advocate use of any soap products on curly hair.
Soap molecules are salts of fatty acids found in plants and animal fats. They are somewhat alkaline and cause the hair to swell and the cuticle to raise up away from the surface of the hair shaft. These molecules are then able to penetrate through the cuticle and into the CMC where they neutralize the fatty acids in the lipid layer, rendering them water soluble. The fatty acids are then rinsed away in the shower and are gone forever. Use of soap to cleanse one’s hair, especially long curly hair, seems to be a really effective way of permanently destroying the cuticle layer and making the hair very highly porous. This is an example of why natural may not always be superior
Porosity and Curly Hair
BTW Dr Ali Syed is the man behind the As I Am line which is pH appropriate for hair, as is Komaza Care.
