The "hair growth serum" many people search for is really a hair-root serum that helps reduce hair fall and helps hair look fuller. It is not a surgical hair transplant. Choosing one that matches the cause of your hair fall is what makes the difference.
The short answer
A good serum matches the cause of your hair fall, has test results behind its ingredients, is gentle on the scalp, and carries a Thai FDA notification number. In the AloEx line, choose like this:
- Hair fall from scalp problems (oiliness, itching, dandruff); you like a light texture → AloEx Hair Serum (50 ml 680 THB / 120 ml 990 THB)
- Hereditary thinning; you want to start on a budget → AloEx Organic Anti Hair Loss Serum (30 ml 295 THB)
- Hair fall from several causes, or premature greying linked to stress → AloEx Organic Intensive Hair Serum (30 ml 590 THB)
Choose a hair-root serum by the cause of your hair fall
Each type of hair fall has a different root cause, so a serum that works for one person may not suit another. Use this table as a starting point.
| Type of hair fall | Recommended serum | Highlights |
|---|---|---|
| Hair fall from an oily, itchy or flaky scalp | AloEx Hair Serum | 15 Thai herbs, light texture, absorbs fastest of the 3 formulas |
| Hereditary thinning, an M-shaped hairline or thinning at the crown | AloEx Organic Anti Hair Loss Serum | Thai herbs from a newer extraction process, plus rosemary oil; the entry-level price |
| Long-term hair fall from several causes, stress, premature greying | AloEx Organic Intensive Hair Serum | 96% active ingredients · Thai herbs + 8 more leading imported extracts |

How to read the ingredients and tell which serum is trustworthy
A trustworthy serum can tell you what is in it, how much, and where it was tested. AloEx serums have 2 main groups of ingredients.
1. Thai herbs tested by TISTR
The base of every AloEx serum is 15 Thai herbs from ancient herbal texts (AloEx Hydrosol Complex), tested by the Thailand Institute of Scientific and Technological Research (TISTR). It inhibited the 5α-reductase enzyme at 89.50% of Finasteride's level and stimulated hair-root cell division at 87.91% of Minoxidil's level1. AloEx Phenolic Complex showed antioxidant activity 371 times that of Trolox in tests by RCBC, Chulalongkorn University1.
2. Leading imported extracts (Intensive formula only)
AloEx Organic Intensive Hair Serum adds 8 more leading imported extracts from Switzerland and Spain: Redensyl™, Capixyl™, Procapil™, Apple Stem Cell, AnaGain™, Hairvivine-Pro™, Densidyl™ and Saw Palmetto, bringing active ingredients to 96% of the formula. Each has its own test results, for example:
- Hairvivine-Pro™: about 39,000 new hairs in 120 days1
- Redensyl™: about 10,200 new hairs in 3 months1
- Densidyl™: helped reduce premature greying linked to stress by up to 24.3% in 140 days1
How is a herbal serum different from Minoxidil and Finasteride?
Minoxidil and Finasteride are medicines used under a doctor's care, and they are the scientific benchmarks in the TISTR test. AloEx's herbal extract delivered about 88–90% of both in the lab1, without the side effects of medicine, and AloEx contains no Minoxidil or Finasteride, which makes it an option for people who want to use something long term. If you are taking medicine prescribed by a doctor, check with your doctor before using them together. Read more in alternatives to Minoxidil.
How to use a hair-root serum for the best results
- Organic Intensive Hair Serum and Organic Anti Hair Loss Serum: shake the bottle and spray directly onto the scalp or hair roots twice a day, morning and before bed. No need to rinse.

Frequently asked questions
Which hair growth serum is best?
Choose a hair-root serum that matches the cause of your hair fall, has test results behind its ingredients, is gentle on the scalp, and carries a Thai FDA notification number. In the AloEx line: for hair fall from scalp problems, choose AloEx Hair Serum; for hereditary thinning on a budget, choose AloEx Organic Anti Hair Loss Serum (295 THB); for hair fall from several causes, or premature greying linked to stress, choose AloEx Organic Intensive Hair Serum (590 THB).
Does a hair growth serum really make new hair grow?
What people call a hair growth serum is a hair-root serum: it helps reduce hair breakage and hair fall and helps hair look fuller with continued use. It is not a surgical hair transplant. Most AloEx users notice less hair fall within 2–3 weeks. Results vary from person to person.
Can women use a hair-root serum?
Yes. All 3 AloEx serum formulas can be used by both women and men.
Do I need to use the serum with a shampoo?
Either one on its own helps reduce hair fall, but using both together shows results faster: the shampoo cleans away oil and residue on the scalp, so the serum can absorb and nourish the hair roots better.
I have hair fall and premature grey hair. Which serum should I use?
We recommend AloEx Organic Intensive Hair Serum, because it contains Densidyl™, whose extract test found it helped reduce premature greying linked to stress by up to 24.3% over 140 days (a test of the extract, not of the finished product).
Where can I buy genuine AloEx serum?
AloEx Hair Serum is available at Watsons, Shopee, Lazada, LINE @AloEx and shop.aloexhair.com. Organic Intensive Hair Serum and Organic Anti Hair Loss Serum are sold through AloEx's online channels, such as Shopee, LINE @AloEx and shop.aloexhair.com.
