The foundation Nutritional gaps start closing. Shedding begins to slow as follicles receive the nutrients they've been missing.
The shift Shedding reduces noticeably. Scalp health improves and dormant follicles begin re-entering the growth phase.
The result Less shedding. Fuller, stronger hair — and 75% of users report shedding has stopped complete
Understanding The Science
Your scalp is missing something.
Your scalp is missing something.
FoliGROWTH® knows exactly what.
Hair loss isn't random — it maps to specific zones on the scalp, each with a distinct root cause. FoliGROWTH® is formulated to target Zone 2, where nutritional deficiencies silently starve follicles and trigger excessive shedding.
Zone 1TM
Hormonal Hair Loss
DHT is quietly shrinking your follicles.
Zone 2TM
Nutritional Hair Loss
Your follicles are starving for nutrients.
Zone 3TM
Inflammatory Hair Loss
Scalp irritation blocks the growth cycle.
Zone 1™ · Hormonal
Your follicles are
Your follicles are
shrinking. And you don't know it.
Testosterone can convert into DHT, which can bind to susceptible hair follicles and gradually shorten the growth cycle — leading to finer, weaker strands and visible thinning, especially at the temples and crown.

Zone 2™ · Nutritional
Your follicles are
Your follicles are
starving. And you don't know it.
Deficiencies in key vitamins, minerals, and nutrients can disrupt the hair growth cycle, leading to increased shedding, diffuse thinning, and weaker growth. Correcting these nutritional gaps helps create the foundation follicles need to grow normally.

Zone 3™ · Inflammatory
Your follicles are
Your follicles are
irritated. And you don't know it.
When the scalp becomes irritated — from stress, immune responses, or product buildup — blood flow to follicles is restricted and the growth cycle breaks down. Calming botanicals and targeted nutrients help restore a healthy scalp environment where hair can grow.

Customer Reviews
Overall rating: 4.9 / 5 from 8 reviews.
I liked the way it felt after using the hairstem serum so far. However, I have not noticed any new growth since 02/13/26, and I'm also waiting to start taking my DHT BLOKER, which I have not received from you. But I have high hopes for these products.
I had the Zone 3 test done with the help of Advanced Tricology since my dermatologist just brushed off my concerns. I was able to speak with someone regarding the results and given suggestions on how to work on the nutritional hair loss. My ferritin level is pretty low as well as vitamin D so it was nice to hear that this may be the cause. I just started supplements and will retest the ferritin in 30 and 90 days

Very helpful. Got a very good snapshot of levels that are not only important for hair health, but overall well being. Very much worthwhile and consultation regarding results also very useful. Definitely worth the investment.

When I did the online quiz, I found out that I have a combination of all the reasons, but I think the hormonal issue was the most difficult. Within a week after the consultation and by using the DHT combo both internally and topically, my scalp was calmer, not burning, and my hair feels thicker and not shedding as much in the shower! The test is a great tool to understand what your body is telling you, but the consultation was beyond helpful and an eye-opener as to where to start immediately. Looking forward to retest in a few months and excited to see the relief! Thank you, Mary!
