Rewiew from Inga: “HAIRTWO products which I have been using approximately for 2 months already and what can I say I’m super excited about this product and I don’t think I’m gonna stop using it anytime soon because my hair condition improves so much it looks so healthy so shiny…”

Hairtwo is a non-medicated formula, free from ingredients known to affect your body’s metabolism or disrupt hormonal balance. It supports your body’s natural processes—working with it, not against it.

We conducted a clinical trial with 30 participants—both men and women aged 18 to 65—experiencing various types of hair loss. Over the course of 150 days, they used our Hairtwo 3D-Bio Boost Serum, and the results speak for themselves:

  • 77% reported reduced hair loss after just 45 days

  • 93% showed a clinically confirmed reduction in hair loss after 150 days

  • 73% experienced a measurable increase in hair density after 150 days

Curious about the details?

Results may vary from person to person, but in our clinical trial, 77% of participants reported reduced hair loss after just 45 days, and 73% experienced a measurable increase in hair density after 150 days.

Interestingly, many of our customers say the first thing they notice is less hair left behind in the shower—often within just a few weeks of consistent use.

Hairtwo® is designed to support nearly all types of hair loss—provided the hair follicles are still capable of growth.
In many cases, follicles remain active during the early stages of hair loss, making it possible to stimulate new growth. That’s why starting treatment early can lead to noticeably better results.

  • No Harmful Chemicals: Aluminum bottles labeled BPA-free are made without Bisphenol A, a chemical often found in plastic that may disrupt hormones.

  • Better for the Environment: Aluminum is highly recyclable and can be reused indefinitely without losing quality—unlike plastic, which degrades with each cycle.

  • Keeps Contents Fresh: Aluminum offers a superior barrier against light, air, and moisture, helping preserve the quality and shelf life of what’s inside.

  • More Durable: Unlike plastic, aluminum doesn’t warp, crack, or leach chemicals over time—especially when exposed to heat or sunlight.

  • Eco-Conscious Appeal: Choosing aluminum supports a more sustainable, lower-waste future, reducing plastic pollution in landfills and oceans.
