How to use it
  1. Mist. Two or three sprays over mid-lengths and ends, from about a hand's width away. Dry or towel-dried hair, not soaking.
  2. Comb through. So it spreads evenly instead of sitting in one place.
  3. Dry as usual. Air dry or blow-dry. No rinsing — it's a leave-in. The whole thing takes about a minute.

What it is

A mist, not an oil.

Most products either coat your hair in buildup or strip it dry. This does neither: it is a featherweight leave-in mist that lays the hair cuticle flat — cutting flyaways and static, adding shine, and leaving a light rose scent behind it. It finishes dry to the touch instead of greasy.

The spray is fine enough to spread evenly instead of landing in heavy wet patches, which is why a couple of pumps covers a whole head. Most people notice smoother hair from the first application, with the full stay-smooth effect building over two to four weeks. Safe for curly, textured and colour-treated hair.

“I really liked this silk serum! It made my hair feel softer, smoother, and much easier to manage. It also helped with frizz and gave my hair a nice shine without making it feel too heavy or greasy. Overall, I'm really happy with it and would definitely recommend it!”

Questions

Everything else

Will this make my hair greasy?

No — it's a weightless leave-in mist, not an oil you pour on. The fine spray lays down a very thin, even layer that dries silky instead of sitting on top of your hair. If coconut or castor oil burned you before, this feels completely different.

Does it work on curly, textured, or color-treated hair?

Yes. It smooths the cuticle without relaxing your pattern — curls stay curls, minus the halo of frizz. Safe for color-treated hair.

How long until I see results?

Flyaways smooth immediately. The full effect — hair that stays smooth through humid days — builds over 2–4 weeks of regular use. That's why most people take the 3-bottle set.

Does it have a scent?

Yes, but lightly — rose. You catch it when you first mist, and it fades to something faint rather than following you round the day. Two of the twenty-two people who rated our manufacturer's listing tagged it “no fragrance”, so treat it as barely-there. It won't fight anything you wear over it.

Ingredients

Aqua (Water), Cetrimonium Chloride, Dimethicone, 1,2-Hexanediol, Hydrolyzed Keratin.

Rose scent. No added colour. If you are sensitive to fragrance, patch test on a small section first.
