Ever wondered about drugstore shampoos versus salon products. Is it really worth it to spend so much more for salon products?
Yes! It all comes down to pH. The natural pH level of the oil in the hair and skin is 5.5 to 4.5. It’s acidic. In order for drugstore shampoos to be cost effective, they’re more alkali. They clean the hair very well, but they strip the natural oils. Ends will be dry and the scalp will be oily because when the product strips the natural pH oils, the body actually increases production. I see it a lot: ends are really dry and scalp hair is really oily. Most salon products are in an acidic pH range. That also protects against color fading, by slowing down dye escaping from hair.
It’s also worth spending the money not just for pH but for the water content. Salon shampoos tend to be more concentrated, so you don’t need to use that much. A 10 ounce bottle should last at least a month. Ohh and BEWARE of the salon brands at your local drug store. They are there illegally and most likely 3 years old ( hair products have a shelf life of about 1 year.
