    Frequently Asked Questions

    What is 40 volume developer used for in hair coloring?

    Iso I Color 40 Volume Creme Developer is a high-lifting developer designed for permanent hair color applications that require maximum lightening power. It's ideal for achieving significant color changes, especially when lifting dark hair several shades lighter or creating bold, vibrant tones. The 40 volume strength provides faster processing times and stronger lifting action compared to lower volumes.

    Is Iso I Color 40 Volume developer safe for sensitive scalp?

    Iso I Color 40 Volume Creme Developer is formulated as a professional-grade product. While the creme base includes conditioning ingredients to minimize scalp irritation, 40 volume is a high-strength developer. We recommend performing a patch test 24-48 hours before application, especially for sensitive or previously compromised scalps. If you have a very sensitive scalp, consult with a professional colorist about whether a lower volume might be more suitable.

    What are the key ingredients in Iso I Color 40 Volume Creme Developer?

    Iso I Color 40 Volume Creme Developer is formulated with hydrogen peroxide as the active ingredient (40 volume = 12% concentration), combined with a conditioning creme base that includes emollients and protective agents. This creme formulation helps reduce dryness and brittleness compared to liquid developers, while the conditioning ingredients support hair health during the coloring process.
