How does it measure up against leading pharmaceutical hair growth products?
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.
What scientific research supports its effectiveness?
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?
How quickly can I expect visible results?
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.
Does it work for all kinds of hair loss?
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.
How to use Extreme Hair Growth Blend?
Why an Aluminum BPA-Free bottle is better than plastic?
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.
