Should You Wash Your Hair Before Coloring It? Here's What You Need to Know
As someone who works with stylists, barbers, and customers every day, one of the most common questions I hear—especially from women preparing for a color appointment—is:
"Should I wash my hair before I get it colored?"
It sounds like a simple question, but the answer can actually impact your color results—and your scalp health.
Short Answer: In Most Cases, No. Don’t Wash It.
It’s generally recommended not to wash your hair right before a coloring session. Here’s why:
1. Natural Oils Protect Your Scalp
When you don’t wash your hair for a day or two before coloring, the natural oils that build up act as a barrier between your scalp and the chemicals in the dye. This reduces irritation, especially if you’re getting a lightener or bleach service.
2. Slightly Dirty Hair Absorbs Color Better
If your hair is squeaky clean, it might not hold onto the color as well—especially if you're using semi-permanent or demi-permanent dye. A little bit of natural buildup can actually help with even dye distribution.
3. But—Don’t Come in With Product Build-Up
There’s a difference between natural oils and heavy styling products like hairspray, gels, and dry shampoo. Too much product can create a barrier that prevents color from penetrating evenly. So, if you’ve loaded your hair with styling products, it's okay to do a gentle wash 24 hours before your appointment (just skip the conditioner).
4. What About Bleaching or Highlighting?
This is where it really matters. Bleach is strong, and having clean hair can make the process more uncomfortable. If you have a sensitive scalp, not washing beforehand can really make a difference in your comfort level.
My Advice to Clients
When someone asks me what to do before a color session, I usually say:
✅ Don't wash your hair the day of the appointment
✅ Avoid heavy product use the day before
✅ If you must wash it, do so 24 hours prior, using a gentle shampoo—no conditioner
