What does the silicone do?

The work. It lays the cuticle flat, which is what stops the frizz and the brush catching. Most serums that call themselves oils contain the same thing and do not say so. No research shows silicone buildup damages the hair itself. The one real objection is fine hair, where too much weighs it down, and two drops answers it.

Will it make my hair greasy or flat?

Not at two drops. The light silicone evaporates and takes the wet look with it. Start on the ends, never the roots.

How do I use it, and can I use it before heat?

Two drops through damp or dry hair, ends first, then style. Yes before heat, and that is the best time: the film sits between the dryer and the hair.

Where do you ship, and what if it does not work for me?

Worldwide, from our US warehouse through our own dedicated network. Orders go out in one to two business days, support answers at any hour. You are covered by the 30 Day Frizz-Free Money Back Guarantee. Use it daily for thirty days. If your hair is not smoother and less frizzy than on day one, tell us and we will refund you.

THE PROBLEM

You keep ironing it flat. It lifts by lunch.

Frizz is not a hair type. It is a cuticle standing open, and heat shuts it for an hour. Every pass of the iron is also why the ends keep snapping off.

01

A straightener flattens the cuticle with heat. It lifts again at the first humidity.

02

A flat iron runs close to the temperature hair does not come back from. Nothing between the two and the cuticle pays.

03

An open cuticle catches on everything, and every snag is a piece that breaks off short.

Lorem ipsum dolor sit amet

how it works

Seal it. Shield it. Keep the length.

Argan Seal Complex™ lays 5% argan oil along the strand, flattens the cuticle, and leaves a film between your hair and what breaks it. Frizz flat today. Less breakage over the months after.

A salon gloss does this and books you again in five weeks. Argan Seal Complex takes ten seconds at your mirror. Keratin lasts four months and takes four months of rules with it. A mask rinses away before the heat goes on. This stays on the hair, which is the only place it can work. It is a silicone serum with argan oil, and we would rather say so than call it an oil.

Same hair. Same light. One pass apart.

No straightener between the frames, no styling, nothing added in post. The frizz is the claim, so the picture carries it on its own.

FAQ

Questions before you buy

It contains silicone. Is that bad for my hair?

No. Silicone is the ingredient doing the work: it lays the cuticle flat, and a flat cuticle is a hair that cannot frizz. No research shows silicone buildup damages the hair itself. The real objection is that too much weighs fine hair down, and the answer is two drops and an ordinary shampoo. Most of the serums that call themselves oils contain the same thing. We would rather tell you.

What is in it?

Five ingredients: Cyclopentasiloxane, Cyclopentasiloxane and Dimethicone, Argania Spinosa Kernel Oil, Parfum, CI 47000. Two silicones, argan oil at 5%, fragrance, and a color that makes the liquid golden and does nothing to your hair. No alcohol, no water.

Will it make my hair greasy?

Not at two drops. The light silicone evaporates and takes the wet look with it. Start at the ends, stay off the roots, and add more only if the ends drink it.

Can I use it before heat?

Yes, and that is the best time. The film goes between the dryer and the hair. Apply to damp hair, let it settle for a moment, then style.

How soon will I see a difference?

The frizz goes on the first pass. The protection builds over about six weeks, which is when most people notice fewer broken pieces. Thicker, fuller-looking hair is the months-long one.

Will it make my hair grow?

Not directly. What it does is stop the ends breaking off, and less breakage means you keep the length you grow. Hair that keeps its length and its ends reads thicker and fuller, and plenty of customers describe it that way after a few months.

How long does a bottle last?

About a month at two drops a day. There is no water in it, so every drop is serum and nothing is padding the bottle.

What if my hair is fine?

Use less, and keep it to the ends. Fine hair is where too much shows, and it is the one real objection to a serum like this. Two drops, mid-lengths down.

FLAT TODAY. FULLER LATER.

Sixty seconds from now, no halo.
