Is this mask good for bleached or heat-damaged hair?

It will soften and detangle dry, rough hair, but it has no protein or bond-building ingredients. Hair that is brittle or breaking needs a treatment with those actives, not just glycerin and collagen.

How many uses does a 30 g pack give?

For shoulder-length hair, expect roughly two to four applications depending on how much you use. Fine or short hair stretches it further; long or thick hair uses it up quickly.

Can I use it on color-treated hair?

Yes. The formula is a rinse-out conditioner with glycerin and collagen and no bleaching agents, so it is safe on color-treated hair. Rinse thoroughly to avoid weighing hair down.

Do I need to use heat with it?

No. Apply to clean damp hair, leave it 10 to 15 minutes, then rinse. A shower cap or warm towel can help, but the instructions do not require it.

How does it compare with a bond-building mask?

Bond builders target broken disulfide bonds inside the hair and cost more. This mask is a surface smoother and moisturizer, so it helps with softness and shine rather than structural repair.

Can I use it every day?

It is marketed for daily care, but most hair does fine with a mask once or twice a week. Daily use on fine hair can leave it limp.

Our take on the Damaged Hair Repair Hair Mask

The Wiyun Hair Mask is a small 30 g rinse-out treatment built on glycerin and collagen, sold as a repair, smoothing and detangling mask for damaged hair. It is a leave-on-for-10-to-15-minutes product for use at home or on the road, and the single-serve size means a few uses at most rather than a tub you keep in the shower. Compared with the large tubs from drugstore and salon brands, it offers a short, low-commitment trial but far less product and a thinner ingredient story: glycerin is a humectant that draws in moisture, and collagen sits on the surface to smooth, but neither rebuilds broken bonds the way bond-building or protein treatments claim to. It suits travelers and shoppers who want to test a mask before committing to a full size.
