Will it show on dark brown or black hair?

Usually only faintly. The pigment sits on the surface, so it reads best on blonde, gray or pre-lightened hair. On dark hair expect a subtle tint at most.

How long does it last?

Until you wash it out. It survives a day or an evening but rubs off on contact and rinses away with shampoo or water, so it is not rain- or sweat-proof.

Does it damage or bleach hair?

No. It contains no ammonia or peroxide and does not lift color; it only coats the surface. The trade-off is that it cannot lighten hair or give a permanent result.

Can I use it on kids?

Many buyers do for parties and play, since it washes out. Do a small patch test first and keep it away from eyes, and expect some transfer onto hands and clothes.

How do I apply it evenly?

Start with dry hair, clip the compact on, and pull through small sections in the same direction. Build in thin layers rather than one heavy pass to avoid patchiness.

Is it the same as hair chalk or spray?

It is closest to hair chalk: a pressed powder rather than a wet spray. It is tidier and more portable than spray, but less pigmented and less durable than a spray or a semi-permanent dye.

Our take on the Blue-Purple Hair Dye Powder

This is a temporary hair color compact: a pressed powder you clip onto dry hair and pull through to deposit blue-purple pigment, then wash out with shampoo or water. It is a touch-up and costume product, not a permanent dye, and it works best on light or pre-lightened hair. Compared with sprays and chalks it is tidier and more portable, but the color payoff on dark hair is weak and it rubs off on hands, pillows and collars. It suits quick, short-lived color for events, photos and kids' play rather than everyday coverage.
