“Shampoos that contain cationic conditioning agents are generally formulated a little lower and deep cleansing shampoos designed to get rid of styling residue are formulated at slightly higher pH to neutralize styling resins.”

If i understood this right, it means that lower ph are usually the most conditioning shampoos, and so the deep cleansing shampoos are the ones with higher ph levels.

So, i used to wear yes to carrots shampoo and as you show in test results, it’s one of the highest ph levels comparing to others from the grocery list.
But this sounds contratictory for me, because yes to carrots shampoo is more like deep conditioning type, because it makes my hair get greasy one day after washing. It feels like it doesn’t clean so well – like a higher level ph shampoo should do.

Anyway don’t take me bad, it’s just my opinion and i’m not doubting about anything you say.

Anyway,i used to wear cheap brands before and my hair would get very dry and frizzy. I started to use salon brands around 5 months ago and now my hair looks much better.

I think that ph level might not be the most damaging agent in a shampoo.
But alcohool is one of the worst, that i can assure you by my own experience.
And overuse of products with wheat protein, mostly indicated for damaged hair can make it get way to dry. I’m not saying that wheat protein is bad,it’s really good to recover damaged hair. But it has to be used moderately and trying to balance protein with conditioning is the best way to keep your hair healthy.

The best shampoo i ever used is Self-Absorbed from Bed head (tigi) – salon brand. it contains SLS.
I’ve been told many times that SLS is highly damaging for hair. So far, the only shampoo i’ve found that does not contain it, was yes to carrots. But this last one doesn’t seem to clean very well, as i mentioned before.

I guess that finding the perfect shampoo is a hard task. Most of them has way to many chemicals and its hard to figure out which of them is putting your hair in a mess.

So,PH level might be a point to consider when getting a new shampoo, but it’s not the only thing to concern about.

And i apologize for my basic english and some grammar mistakes, this is not my native laguage.

Thank you!!
