Can You Wash, Heat Style and Color Human Hair Extensions?

Updated 2026-09-25. By Devan, hair extension specialist.

Yes. 100% human hair extensions can be washed 2 to 3 times a week, blow dried, curled and straightened like your own hair using heat protection. They can be toned darker by a professional, but lightening is not recommended because it weakens the hair.

How should I wash extensions?

Wash with your head upright or tilted back, not upside down, using sulfate-free shampoo at the roots and conditioner on the lengths only. Keep conditioner away from tapes and beads.

What heat is safe?

Use heat protection and stay at or below about 350F (180C).
