For hair that's been through a lot

You're allowed to love the weight loss and miss your hair.

If the brush is fuller than it should be and the ponytail needs an extra loop, you're not imagining it and you're not being vain.

Shedding during and after rapid weight loss is common. But it doesn't have to be. Give your scalp the slow, nourishing ritual it deserves and support your hair from root to tip.

In their own words

They went through it too.

We never made a product for weight-loss shedding. These reviews arrived on their own, unprompted, from verified buyers. We're quoting them exactly as written.

“I've had hair loss recently (after being on a GLP1) and I've noticed that not as much seems to come out while I'm shampooing or brushing my hair after washing (it's been the only thing I've changed). It's got a lovely smell to it so also feels quite therapeutic when using.”

“I lost a whole heap of weight and all of my hair fell out. It was soooooo thin. Started using Hinu about 6 months ago and my fullness has all come back. And I'm still noticing new baby hairs all the time. Plus - it smells delicious!”

“After experiencing hair loss and hair thinning after weight loss surgery I tried many different hair growth oils but none seemed to work. Until I tried Hinu. This is such a beautiful blend of ingredients that has not only helped with hair growth but has improved the overall health of my hair.”

The part nobody warns you about

Nobody warned you about the shower.

The compliments, yes. The new clothes, the double takes, the friend who grabs your arm and says you look incredible. But not the moment you run your fingers through wet hair and come away with more than you should. Not the extra loop in the hair tie. Not standing under the bathroom light tilting your head, wondering whether your part was always that wide.

And here's the unfair bit. You don't feel allowed to mind. You chose this. It's working. So you smile, say thank you, and quietly empty the brush again.

So let's say the thing out loud: you're allowed to be thrilled about your body and heartbroken about your hair at the same time. Both are true. Neither cancels the other. And if you found your way here somewhere between a GLP-1 medication and a blocked shower drain, you're in very good company. Some of our customers arrived exactly the same way.

What's actually happening up there

Your hair is running about three months behind the rest of you.

Here's the short version of what a trichology textbook would say. At any moment, roughly 85 per cent of the hairs on your head are growing and about 15 per cent are resting. When your body goes through something big and fast, it quietly moves more hairs than usual into rest. Rapid weight loss sits on dermatology's own list of ordinary triggers for this, right alongside having a baby and recovering from an operation. Familiar company. Temporary company.

And here's the catch that explains everything. A resting hair doesn't fall out straight away. It sits in the follicle for two to four months, then lets go. So the shedding arrives on a delay, right when the scales are finally moving and everyone keeps telling you how amazing you look. Your hair isn't reacting to this week. It's reacting to the week your body changed gear, months ago.

Two things about that are genuinely comforting. First, this is shedding, not balding. The follicles underneath are alive and simply on pause; nothing is scarred, nothing is gone for good. Second, this kind of shedding winds down on its own as your body settles into its new normal. Researchers are still working out whether the medication itself plays any part; what almost everyone agrees on is that the bigger driver is the speed of the change. Which is why nothing on this page will suggest you change what's working. Keep going. Your hair isn't asking you to stop. It's asking you to wait, and to be kind to it in the meantime.

Shedding, not balding. The follicles are resting, not gone.

The part you can control

So what do you actually do with the waiting?

01 · GENTLENESS

Handle it kindly

Hair mid-shed is fragile hair. Ease up on heat, tight ponytails and rough towel-drying. Every strand you don't snap is a strand you keep.

02 · NOURISHMENT

Feed it first

Smaller meals mean your body is prioritising, and hair is generous; it always gives its share away first. Protein at every meal is the kindest thing on any list.

03 · RITUAL

A moment that feels like care

Ten minutes, once a week, of warm oil and slow scalp massage. It nourishes the scalp your hair grows from, and it gives you one moment in the week where your hair is something you tend, not something you grieve.

And the lag works both ways: the shedding you see today started months ago, and the care you give your scalp today is what you'll be seeing months from now. Start the good habit tonight.

The first two are yours. The third one is ours.

Where the name comes from

“Hinu” is the Māori word for oil.

HINU began with founder Allie Cameron and the hair-oiling traditions of her Māori heritage in New Zealand, where oiling hair has been an act of care passed between generations for as long as anyone can remember. Not a treatment. A ritual. Something you do for someone you love, or for yourself, slowly, with your hands.

That's the spirit the Hair Growth Oil was blended in: 18 botanical oils and extracts, chosen to nourish the scalp and leave lengths feeling soft, strong and cared for. It was never designed for any medication, any diagnosis, any trend. It was designed for hair that's been through a lot. Which, some seasons, is all of us.

“Rawe te hinu nei mō ōku makawe! My poor hair has gone through a lot in the past year with weightloss, pregnancy and then a bad decision of getting highlights that bleached my hair to a point of breakage :( I have chopped off the lifeless hair and started using this hair oil before every wash. It has made such a difference to my hair. Ngā mihi nui x”

What's in the bottle

18 botanicals. 15 certified organic. Nothing you'd need to google nervously.

Amla and false daisy, treasured in traditional hair oiling for centuries. Black sesame, avocado and tsubaki to nourish. Rosemary, peppermint and black pepper to leave the scalp feeling awake and cared for. Lavender, cedarwood, sandalwood and geranium, which is why every second review mentions the smell. Lightweight enough to wash out completely, gentle enough for sensitive scalps, kind enough to use on the week you need kindness most.

The full ingredient list, in label order, is on our product page. Review it first if you have sensitivities, and stop using the oil if irritation occurs.

One bottle. One night a week. That's the whole ask.

The whole ritual, honestly

The Sunday-night ritual

1

Pour

2 to 3 droppers into your palms, onto a dry scalp.

2

Massage

Work it slowly into the scalp with your fingertips, then run what's left through your mids and ends. Take your time. This part is for you as much as your hair.

3

Sleep on it

Leave it at least an hour, or overnight on an old pillowcase, then shampoo out as normal. Soft, clean, never greasy.

Already juggling protein targets, appointments and everything else? This is the one thing on your list that only happens once a week.

Honest timelines

A lot of shedding seasons. A lot of endings like these.

All the regrowth!!

Last time I washed my hair I had to laugh, there's a porcupine thing going on up top - so much regrowth!!! All the little hairs growing, about 3 inches of growth - right where I'd noticed thinning.

Postpartum Miracle

I couldn't believe how much hair I was losing and every brush and wash would end up almost in tears. Purchased Hinu after reading the reviews and within a month had noticeably less hair loss.

Hinu saved my hair!!!

It was dry, brittle and falling out in clumps - I literally thought I was going to go bald! Within a week of using Hinu hair oil and scalp massager my hair stopped falling out in large amounts… I've got a forest of baby hairs sprouting up all over my head!!!

Noticeable difference

Within the first week my hair loss reduced by half. And now I'm not even noticing any hair breakage and only a normal amount of hair loss.

Good results

My hair was falling due to hormonal issues, I wasn't sure if this oil would help but I gave it a try… the hair is not falling in clumps anymore, feels stronger and shinier.

Postpartum hair loss was real for me and it started impacting my self esteem. Within 2 weeks of using this I saw a noticeable difference to my hair loss and scalp health.

Questions, answered honestly

Will this interfere with my weight-loss medication or my results?

No. It's a botanical oil that goes on your scalp and washes out in the shower. You don't swallow it, it isn't a supplement, and nothing about your treatment, your dose or your routine changes. Your program stays exactly as your doctor set it.

Do I really only use it once a week?

Once a week is the ritual: 2 to 3 droppers on a dry scalp, at least an hour or overnight, then shampoo out. If you like, a few drops on the ends between washes keeps lengths soft. But no, this is not another daily task. You have enough of those.

Is it greasy? I've been burnt by hair oils before.

It's a pre-wash treatment, not a leave-in. The oil does its work before shampoo day and washes out completely. You wear the results, not the oil.

Does it stop the shedding itself?

Shedding after rapid weight loss is your hair cycle responding to how fast your body changed, and it settles on its own as your body does. No oil changes that clock, and we won't tell you otherwise. What our customers consistently report is the part care can touch: softer, stronger-feeling hair, less snapping at the brush, and a scalp that feels looked after while the cycle rights itself. Their words are all over this page.

How long until I notice anything?

Honestly, it varies, and anyone who promises you a date is selling you something. Some customers report changes in the brush within a few weeks; fuller-looking hair takes months, because that's how fast hair grows. The lag that delayed your shedding delays the good news too, which is the best reason to start now rather than later. And the 60 days covers you while you find out.

When is shedding worth mentioning to a doctor?

Shedding after rapid weight loss is usually temporary and settles as your body adjusts. If yours is patchy rather than all-over, came on very suddenly, is still heavy after six months or so, or is simply weighing on you, mention it to your GP next time you're in. Not because anything is wrong, but because reassurance is lovely and you deserve some.
