I relaxed my hair two weeks ago and I neutralised as usual. The following week I washed my hair using my Nexxus Shampoo and deep conditioned with the Nexxus Humectress conditioner. I was feeling lazy so I airdried my hair. I forgot to apply leave ins and was not happy with how my hair felt. So the next day I washed it again but this time I didn't have my shampoo on hand and used what I had in the bathroom which was my ORS Professional Neutralising Shampoo. I followed up with my regular conditioner and when I roller set my hair, it felt as if I had relaxed my hair that day. That fresh relaxer look usually disappears for me after that first wash. My hair also kept that look for the entire week. My hair felt moisturised for days after my wash.
For my 2nd week post relaxer wash, I decided to also shampoo with the Neutralising Shampoo. I airdried my hair this time and then flat ironed. Again, my hair felt like I had relaxed on that day. The experience got me thinking about why a neutralising shampoo would have such an effect on my hair and the only answer I could come up with is that it has to be something about the pH.
I was inspired to start researching about pH. I found that hair should have a pH of 4.5 and 5.5. Products that keep our hair in that range are therefore best for our hair. According to the Science of Black Hair, we should work down in acidity, ending with the most acidic products as this seals our cuticle and makes our hair smoother. I know understand why some girls do a ACV rinse and it has a pH of about 4 when it is diluted.
According to the Science of Black Hair we should be using a shampoo, a conditioner and a moisturiser that are all pH balanced.
This is something I am going to be looking more into. Do any of you ladies pay attention to the pH of your products?
