Different from the rest
"Too soon to see new growth but of the numerous products I’ve tried, this one does make my fine thinning hair look and feel fuller. It does seep into scalp with no residue so dont need to “wash out”."
Actsyl-3 Serum
For hair that's shedding more than it used to. Actsyl-3 is a lightweight daily serum with Redensyl (3%) and Capixyl (2%). Shedding often shows up a few months after a life change such as weight loss, GLP-1 medications, a new baby, or perimenopause, and it can also come with time.
Most of us put years of care into our skin. Hair deserves the same attention, because thin, dull hair adds years just as quickly. Actsyl-3 absorbs within seconds and leaves no residue, so you can style as usual.
What to expect
- Weeks 1 to 2: softer, more manageable hair.
- Weeks 2 to 4: most people see less hair in the shower and the brush.
- Weeks 6 to 8: more shine and body.
- Three months on: fuller-looking hair with consistent daily use.
Results vary from person to person.
Why customers stay with it
- A light texture that never feels greasy.
- Non-hormonal and naturally derived.
- Works alongside your current products.
- Made in a GMP-certified, solar-powered facility in Los Angeles.

How to Use
Apply one to two droppers directly to the scalp on clean hair, either dry or towel-dried. Massage gently with your fingertips, paying extra attention to areas of concern. The serum absorbs quickly, so you can style as usual straight afterward.
Use once a day for best results.
Key Ingredients
Redensyl® (3%)
A complex of larch and green tea extracts with glycine and zinc, chosen to help reduce visible shedding.
Capixyl™ (2%)
Acetyl tetrapeptide-3 paired with red clover extract, for stronger, fuller-looking hair.
Panthenol (Pro-Vitamin B5)
Draws moisture into hair and scalp and improves elasticity, which helps hair resist breakage.
Apple Fruit Extract
Rich in antioxidants that help protect hair from pollution and everyday wear.
Biotin
A B-vitamin long associated with strong, healthy-looking hair.
Menthol
Gives a light, cooling feel on the scalp with each application.
What to Expect
The experience
Actsyl-3 comes in a black glass dropper bottle that protects the formula from light, which allows for fewer preservatives. The texture sits between a serum and a light conditioner. It spreads easily across the scalp without running and never feels sticky. One to two droppers cover the whole scalp, and the fresh, clean scent fades quickly.
Results over time
Most people notice less shedding within the first 2 to 4 weeks. Softness and shine follow, and fuller-looking hair builds over several months of daily use. Results vary from person to person.
What customers tell us
Many customers say their hair was drier than they realized before they started. With regular use, they describe hair that feels softer and more hydrated and holds a style longer.

Waiting for results
"So far I've been using this product for 2 months (admittedly not every single day) and I don't see noticable results yet but I'll continue for another few months before deciding if this works for me. It is easy to apply with little residue and smells very nice."
Hair Serum
"I am using the hair serum, shampoo, and leavin conditioner. My hairdresser asked me what I was doing because my hair felt thicker. I also love the clean smell."
