We know you've been burned before. Shampoos that promised the world and delivered nothing. Here's what makes this different.
Rosemary oil was tested head-to-head against minoxidil in a clinical trial. After 6 months, both groups saw the same hair count increase. No prescription needed.

Rosemary stimulates growth. Hydrolyzed keratin rebuilds what's already there. Studies show keratin increases hair tensile strength by 21.66%. Stronger hair = less breakage = more length.
Bian et al., Molecules, 2025
No prescription. No dread shed. Stop using it anytime without losing progress. This isn't a drug—it's a shampoo that actually works.
Sulfates strip keratin from your hair. Most shampoos contain them. Alyra doesn't. We're not going to rebuild your hair just to tear it down again.
I was very sceptical... baby hairs everywhere, barely any hair falling out now!!!
