Low pH Shampoos
It infuses the hair shaft with moisturizing ingredients like panthenol, glycerin, aloe, olive oil, shea butter, etc. This shampoo would be good regular use on those with dry or damaged hair.
Dry Shampoos – These are waterless cleansers that are best used in between wash days to remove excess oils without going through the whole wash day process. Example: Oscar Blandi Pronto Dry Shampoo
My recommendation would be to add the one type of shampoo you could get the most use of to your hair regimen (the “regular use” shampoos, like the low pH, moisturizing, smoothing or volumizing). You can add the other “special occasion” shampoos (anti-dandruff, chelating, or clarifying) to your regimen, if/when necessary.
What type of shampoo do you use?
