No visible improvement
I am using the hair gain extract for over a year. No improvements to report. Oral minoxidil has been keeping hair from falling but this extract hasn’t helped as far as I can tell.

Already working
It’s simple-i already see results and i just started bottle #2. You can actually see the small hairs that have grown. There’s a difference in my hair. I fell away from this company due to technical difficulties & my move and my hair paid the price for it. I’m back and I couldn’t be happier, Yes, it is pricey, and just got pricier which i don't love but if you can afford it, of all the things you will spend your money on in your hair journey this one WILL actually yield results.

Best Hair Growth product ever
I never write reviews ! However my experience with Harklinikkin is exceptional. I’m on bottle 21, and everyone including my hairdresser has noticed improvement to thickness and texture of my hair. Thank you!
