Description
Add an evening step to your routine with this AMAINKI hair serum. The 60 ml bottle combines rosemary oil, batana oil and biotin, in a light base that you spray onto the scalp.
The micro-diffuser nozzle releases a fine mist, so you can aim at the roots without soaking your hair. The texture is not greasy and needs no rinsing: you spray, massage with your fingertips, and leave it on overnight. The brand presents it as a leave-in scalp care for women and men.
Use this serum every evening; one bottle lasts about two months. The brand notes that a slight warm sensation may follow application, and recommends asking a health professional before buying if you have any concern about your scalp or hair.

Our review of this hair serum
Review written by the Aura Capillaire team · Updated on 20 September 2026
We studied this hair serum, its data sheet and the competing versions to pick out its strengths and limits.
Strong points
- Rosemary, batana and biotin together: three very popular ingredients in a single formula.
- A light texture that is not greasy: the serum dries without leaving a film on the hair.
- A micro-diffuser nozzle: the mist reaches the roots without wetting the lengths.
- Two months per bottle: 60 ml at one application each evening, no rinsing.
Things to know
- A warm sensation may follow application: the brand describes it as normal: space out applications if it bothers you.
- A cosmetic care, not a treatment: if you have a concern about your scalp or hair, ask a health professional before buying.
Where we lean: for a simple evening step based on rosemary and batana, this spray hair serum earns its place in a routine. If you prefer a roller application, more precise on one area, the WishCare roll-on below does that. More of the range is in our hair serums.

AMAINKI, WishCare, HaloGrow or Be Bodywise?
The same type of serum comes from several brands. Here is how this bottle compares with the three other most-requested versions.
| Serum | Format | Highlighted ingredients | Ideal for |
|---|---|---|---|
| AMAINKI AMAINKI · this serum |
60 ml spray | Rosemary, batana | Evening step |
| WishCare WishCare |
Serum | Rosemary, caffeine | Full formula |
| HaloGrow HaloGrow |
Spray | Oils | Wide application |
| Be Bodywise Be Bodywise |
Roll-on | Redensyl | Targeted area |
The WishCare rosemary serum stacks up more ingredients highlighted by the brand, including caffeine and peptides. Its longer list appeals to people who compare formulas. This hair serum keeps a shorter composition, centred on rosemary and batana.
The HaloGrow spray is also sprayed onto the scalp, in a similar size. Its mist is wider, which is quick and also reaches the lengths. The micro-diffuser nozzle of this hair serum aims better at the roots.
The Be Bodywise roll-on is applied with a roller, ball against the scalp, which suits a specific area such as a parting. Application takes longer over the whole head. A spray covers the whole scalp in a few pumps.
Your questions about this hair serum
How do you apply this hair serum in the evening?
Spray onto dry hair, at scalp level, parting by parting, then massage with your fingertips for a minute. It is not rinsed out and dries without leaving a film. One application each evening is enough, according to the brand.
Can you use it on coloured or straightened hair?
The formula is a leave-in cosmetic, so it is compatible with coloured hair. Test it first in the crook of your elbow if your scalp reacts quickly. If you are undergoing a treatment or are pregnant, ask a health professional for advice.
What is the difference with the WishCare serum?
WishCare highlights a longer list of ingredients, caffeine included, in a dropper bottle. This AMAINKI hair serum rests on three well-known ingredients and a spray nozzle. The choice is between a fuller formula and a quick step.
