Frequently Asked Questions
Can I use regular conditioners on color-treated extensions?
You can, but it’s better to use sulfate- and salt-free formulas made for color-treated or keratin-treated hair. Regular conditioners with strong sulfates or salt can fade dye and weaken keratin bonds; heavier, protein-rich formulas can also change the feel of some extensions.
How often should I condition dyed extensions?
Rinse-out conditioning is recommended after every wash (typically 1–3 times weekly depending on lifestyle). Use a leave-in mist between washes to maintain softness, reduce tangles and protect color. Avoid over-conditioning at the roots of sewn or tape-in extensions—apply conditioner an inch from the bonds to prevent slippage.
Should extensions get protein or moisture?
Both are important, but balance matters. Moisture-focused, protein-free conditioners are safer as regular maintenance for color-treated extensions. Use light protein treatments sparingly if the hair feels weak or gummy—overdoing protein can make extensions stiff. Alternate moisturizing treatments with occasional protein-based masks if needed.
