Goldwell Dualsenses Just Smooth 60 Sec. Treatment Mask - 200ml

While the product is designed for 60 seconds, leaving it on for 2-3 minutes is safe if you feel your hair needs extra nourishment, but it is not strictly necessary.

Yes, the Dualsenses series is generally formulated to be gentle on color-treated hair.

It can be used once or twice a week depending on the current condition and dryness of your hair.

The primary focus is on hydration and smoothing with kukui nut oil, rather than being a heavy protein-reconstructive treatment.

While it improves resilience to damage and makes hair feel smoother, it cannot permanently repair split ends; it temporarily masks their appearance.

It is generally safe for high-quality human hair extensions, but avoid applying directly to the bonds or tapes.

Apply a smaller amount and focus strictly on the mid-lengths to ends, avoiding the scalp area.

Ensure hair is towel-dried before application; if hair is dripping wet, the mask may slip off before absorbing.

Ensure you are rinsing thoroughly and potentially pair with a smoothing leave-in serum for extra protection.
