Both products use the same clinically-tested Bio-Pilixin® formula. The Activation Serum comes with a pipette that covers your whole scalp, while the Hairline Booster has a six-ball rollerball applicator that zeroes in on your corners and temples.

 Your first purchase includes everything you need: the hair nutrient tablets, precision rollerball applicator and a starter cartridge inside. When it's time to refill (about a month later), simply pop in a new cartridge. You can grab refill cartridges here.

1. Clean & Dry Scalp: Ensure your hairline area is clean and dry before application for optimal serum intake.

2. Prep the tool: Remove the lid to reveal the 6-ball roller and turn the bottom of the pen to “ON.”

3. Apply the serum: Place the roller on the hairline, press once, and massage in slow circles across the front, corners, and temples. Press again if needed.

4. Massage & finish: Continue massaging for 2 minutes. Switch to “OFF” and replace the cap securely.

5. Let it stay: Do not rinse for at least 6 hours. Let the product dry fully before styling or applying other products.

6. Frequency: Use once daily, ideally in the evening, for consistent results.

You don't have to choose, they're designed to work together. Use the Activation Serum to treat your entire scalp and the Hairline Booster to target receding corners with precision.

If choosing just one: Pick the Activation Serum for overall thinning or crown concerns. Choose the Hairline Booster if your main issue is a receding hairline.

The Hairline Booster is specially designed for the hairline area. We do not recommend using it in other spots as the micro-rollers can pull hair if used on denser areas of the scalp.

The Hairline Booster applicator is built to last. With proper care, you can expect about 3 years of use.

If used once or twice daily, a cartridge should last around 1-2 months.

The Hairline Booster works best as an early intervention tool when follicles are still intact. It's designed to help maintain the hair you currently have rather than restore areas that have been bare for extended periods.

Wipe the roller balls with an alcohol swab when replacing cartridges to keep your applicator clean and hygienic.

Yes! The Hairline Booster works for women too. While men more commonly experience receding hairlines, women can face similar issues from traction alopecia, postpartum hair loss, or menopause-related thinning.

None of our products contain any known natural DHT blockers. Although these ingredients may be effective in supporting hair regrowth, we are awaiting more long-term research to be done on natural DHT blockers for supplements before incorporating them into our supplement formulas. In fact, many of these plant extracts are banned in Denmark, due to a lack of evidence around them.
