Regular shampoos are often loaded with harsh chemicals. Some people are more sensitive than others, but if you notice flaking, itching, or discomfort, a cheap shampoo might be to blame. Parabens and phosphates in drugstore shampoo can irritate your hair, scalp, and eyes. Ouch!Unlike cheapie shampoos which rely on irritating synthetic detergents, salon formulas may offer safer, healthier ingredients. Check the label to see what’s really inside the bottle. A quality shampoo will skip the chemical ingredients in favor of gentler cleansers.Another thing to look out for with regular shampoo is sulfates. Avoiding sulfates is the #1 way to keep hair healthy looking. Sulfates strip hair’s natural oils, leaving your tresses fragile, dull, and dry. To keep hair strong and healthy, look for a salon shampoo that’s sulfate free.Obviously not all salon brands are created equal, so be sure to read the ingredients and skip those heavy on the chemicals.
