Gisou sells two hair oils, and the difference between them is more than a matter of bottle size. One is a rich, classic oil built for hydration and frizz control; the other is a weightless drops formula designed for shine without heaviness. Choosing well comes down to three questions: how thick your hair is, how quickly it starts to look greasy, and which moment of the routine you want the oil for. This guide answers those questions, compares the two formulas side by side and explains where the Honey Hair Oil Duo fits.
What the two oils share
Both formulas are powered by Mirsalehi Honey and the Bee Garden Oil Blend, so they share the same honey-led character: a soft, glossy finish and a light honey scent rather than a heavy, perfumed oil. Both can go on damp or dry hair, and both are designed to be used in small amounts. The difference is in weight and intent rather than in origin.
Where they part company is texture. The Honey Infused Hair Oil is the richer of the two and works as a treatment as much as a finish. The Collagen Drops feel closer to a serum: fast-absorbing, lightweight and built around instant shine and a visibly plumped look. If you are unsure which formula suits you, your hair density is a better guide than your hair length: two people with the same length can need different oils because one has more strand volume to carry a richer formula.
Honey Infused Hair Oil: the rich, classic option
The Honey Infused Hair Oil is the product that started the brand and the one marked award-winning on its product page. It comes in 50ml and 20ml sizes and is powered by Mirsalehi Honey and Bee Garden Oils. Gisou describes it as delivering intense hydration, instant shine, heat protection and lasting frizz control. It can be used three ways: before styling as a protective layer, after styling to tame and gloss, and overnight as a treatment to be washed out the next morning. If you want the long version of that routine, see our complete guide to the Honey Infused Hair Oil.
It suits medium to thick hair, coarse or dry hair, and anyone whose main complaint is frizz and dullness rather than flatness. On fine hair it can still work, but only in very small amounts and only on the ends.
Honey Gloss Collagen Drops: the lightweight option
The Honey Gloss Collagen Drops Hair Oil is a 20ml drops formula built on Mirsalehi Honey and collagen active, designed to hydrate, visibly plump and boost shine. Gisou positions it for fine to medium hair, while noting that it works for all hair types. The texture is light and fast-absorbing, the pack is made for on-the-go use, and the finish is glossy without weight.
This is the one to choose if your hair goes flat under richer products, if you want shine on a finished style without disturbing the shape, or if you have avoided hair oil in the past because it made your roots look greasy. It is also the more practical option for refreshing second-day ends, where a couple of drops restore the look of a fresh blow-dry.
Hair type and use case, side by side
The table below turns those differences into a decision. Read the middle column first if you already know your hair type.
| Hair profile or moment | Better match | Why |
|---|---|---|
| Fine hair that flattens easily | Honey Gloss Collagen Drops | Lightweight and fast-absorbing, so shine arrives without weight |
| Medium to thick, dry or frizz-prone | Honey Infused Hair Oil | Richer formula for hydration and lasting frizz control |
| An overnight treatment | Honey Infused Hair Oil | Rich enough to sit on the hair and be washed out the next day |
| Shine on a finished style | Honey Gloss Collagen Drops | Keeps movement and does not disturb the shape |
| Undecided, or want one of each | Honey Hair Oil Duo | Full-size Drops plus a travel-size Hair Oil |
The duo, and when it makes sense
The Honey Hair Oil Duo pairs a full-size bottle of the Collagen Drops with a travel-size Honey Infused Hair Oil. Gisou presents it as two routines in one: the Drops as the everyday oil for fine to medium hair, and the Hair Oil as the richer product for medium to thick hair and for overnight use. If your hair sits somewhere in the middle, or if your routine changes with the season, the duo lets you test both formulas without buying two full bottles. It also divides neatly between the shelf and a travel bag, with the Drops staying at home and the smaller oil coming with you.
Practical notes before you buy
A few habits make either oil easier to live with. Apply to the mid-lengths and ends rather than the scalp, add a few drops at a time and only top up if the hair still looks dry, and remember that damp hair absorbs oil more evenly than dry hair. There is no need to use both formulas in the same routine: layering them tends to make fine hair heavy and adds little to the finish. Whichever you choose, it is at its most effective as the last step after styling, unless you are using it overnight or as pre-styling protection. Use less than you think you need on the first application, especially with the richer oil, because it is easier to add a drop than to remove one.
Product note. For most readers the choice is between the Honey Infused Hair Oil and the Honey Gloss Collagen Drops Hair Oil, and the answer follows your hair type rather than the season. If you would rather not decide yet, the Honey Hair Oil Duo contains a full-size Drops bottle and a travel-size Hair Oil, which covers both the everyday and the overnight job.
