Is Excellence 5 Lysebrun safe for use on sensitive or chemically damaged hair?

The product contains hydrogen peroxide, chlorhexidine digluconate, fragrance and other surfactants that can irritate a sensitive scalp, so a patch test is essential; while conditioning agents like hydrolyzed oats help reduce dryness, users with very fragile or previously treated hair should proceed with caution.

What role does hydrogen peroxide play in this hair‑bleaching formula?

Hydrogen peroxide acts as the primary oxidizing agent, opening the hair cuticle and breaking down natural pigment to achieve the light‑brown shade, while also activating the other chemicals that set the color.

Does the formula contain any ingredients that are considered harsh or potentially irritating?

Yes, it includes chlorine‑based preservative chlorhexidine digluconate, hexadimethrine chloride, propylene glycol, fragrance (parfum) and titanium dioxide, all of which are known to cause irritation or allergic reactions in some individuals.

The formula incorporates hydrogen peroxide for lift, along with preservatives like chlorhexidine digluconate, pentasodium pentetate, and a fragrance mixture, which together deliver strong lightening results but may provoke irritation on sensitive scalps. Although it is labeled gluten‑free, it contains several synthetic chemicals, including titanium dioxide pigment, dimethicone, and hexadimethrine chloride, that some users may prefer to avoid.
