I just recently got my hair highlighted again and my stylist suggested to me to not use a stripper shampoo or conditioner, because my color never last long. How do I know which ones will enrich the color of my hair and which ones will damage the color? Please help.

Go to any store that sells a variety of shampoos and conditioners. Find one that says “color safe” or “for colored hair” or “for blondes/brunettes/redheads” or something like that.
First, go to any pharmacy or store that sells shampoo.
Second, look for shampoo bottles that say “specially made for colored hair” or something along those lines.
Last, buy the best brand or which has a good scent
