Finally something that is not greasy
Every serum I have tried before left my roots looking oily by the afternoon. Two pumps of this on the ends and my hair still has movement the next day.

Cut my styling time down
I use it straight out of the shower before I blow dry. The comb glides through and the whole thing is faster than it used to be.

Good on colour-treated hair
My hair is bleached and usually feels like straw by the ends. This softened it without making it limp, which is the balance I could never find.

Frizz is genuinely gone
I live somewhere humid and my hair usually puffs up within an hour of leaving the house. This is the first thing that has actually held all day.

My curls kept their shape
Most serums flatten my curls out completely. This one added shine without dragging them down, and the definition is still there the next morning.

The ends look healthy again
My ends were always dry and splitting no matter what I used. Three weeks in and they look thicker and far less frayed than they did.

A little goes a long way
Really pleased with it. Only note is that the pump gives a generous dose, so start with less than you think you need.

My stylist noticed
She asked what I had changed before I said anything. Been through two bottles now and I keep one at home and one at work.

For: all hair types. 100 ml / 3.38 fl oz.
Directions: on damp hair, pump 2–4 doses into your palms, rub together and work through the mid-lengths and ends. Comb through to distribute. Style as usual. On dry hair, use two pumps to tame frizz and flyaways.
Note: for external use only. Avoid contact with eyes. Start at two pumps and add more if you need it — fine hair rarely wants the full four. Discontinue if irritation occurs.

Why a serum?
Masks wash out. Oils sit on top. A serum stays on the strand after styling — which is where smoothness actually has to survive.
Smoother hair
without the weight.Because slip should not
cost you volume.
Most smoothing serums buy their slip with heavy silicones that build up and flatten hair over time. This one leans on plant oils — flaxseed, grape seed and jojoba — with squalane and glycerin for softness, and Auto Detangle Technology to cut the friction that causes frizz.

Frequently Asked Questions
1. How much should I use?
Two to four pumps for most hair. Fine or short hair usually needs two; long, thick or very dry hair will want the full four. Start at the lower end and add more if you need it — over-applying is what makes a serum feel greasy.
2. Wet hair or dry hair?
Both. On damp hair after washing it acts as a detangler and heat buffer before styling. On dry hair a small amount smooths frizz and flyaways during the day.
3. Will it weigh my hair down?
It is built to avoid that. Vegetable squalane is light and fast-absorbing rather than film-forming, so it softens without the buildup heavier silicone serums leave behind. Apply from the mid-lengths down and keep it off the roots.
4. Is it safe for coloured or bleached hair?
Yes. It is formulated for all hair types including chemically treated hair, and it is not a clarifying product, so it will not strip colour.
5. What is Auto Detangle Technology?
It is the conditioning system the serum is built around. It works on the surface charge of the hair to reduce friction between strands — which is what makes hair feel smoother, comb more easily and frizz less in humidity.
6. Does it protect against heat?
It buffers the hair during blow-drying and reduces the time you need to spend on heat, which is where most damage accumulates. If you use very high heat regularly, pair it with a dedicated heat protectant.
7. How long does one bottle last?
A 100 ml bottle holds roughly 100 pumps. At three pumps a day, used daily, that is about a month.
8. What is in it?
Water, glycerin, hydrogenated castor oil, 1,2-hexanediol, carbomer, arginine, flaxseed oil, grape seed oil, jojoba seed oil and vegetable squalane. The omega 3, 6 and 9 come from the flaxseed, grape seed and jojoba oils. Full list is printed on every bottle.
9. Can I cancel a subscription?
Yes, anytime, with no cancellation fee. Manage or cancel from your account, or contact support@tryaitch2.com.
