Do Hair Growth Supplements Work? Here's What 90 Days Showed Us

This summer, we launched our hair support formulas for women and men. Our product development team spent months researching, sourcing, and testing ingredients for these formulas, and we were confident they could be a breakthrough in supporting thinning hair.*

But the question remained:

Do hair growth supplements work? 

Today, our 90-day at-home study results show our formulas not only help support thicker, fuller-looking hair, but also restore our customers' confidence in their appearance.*

We’ll get to the results shortly, but first, here’s the background on our study. 

Our cohort included 26 women and 13 men based in California with various occupations, including fitness instructors, therapists, bankers, real estate agents and more. 

Their ages ranged from 27-67, but most are in their 40s and 50s. They have a variety of hair types, textures, and colors.

Regardless of their age, backgrounds, and hair types, many of our participants were experiencing the same issue: hair that's thinning, shedding, or breaking.

Common troublesome spots included crowns, temples, and parts. Apart from the normal aging process and genetics, many self-reported specific causes of hair issues: 

• Perimenopause and menopause

• Previous GLP-1 use

• Past COVID

• Postpartum

Many also cited secondary effects of thinning hair like lack of confidence in their appearance. 

Each participant in our study took the recommended dose (2 capsules per day) of either Dynamic Hair Energy for Women or Dynamic Hair Energy for Men for 90 days. 

We interviewed and surveyed each participant at the beginning of the 90-day trial to gather data on their concerns, their stories, and their expectations, and again after the 90-day mark.

And of course, we photographed each of them at Day 1 and Day 90, which brings us to the results. 

Our women’s group reported: 

• 94% thicker, fuller-looking hair†

• 92% healthier hair†

• 94% new hair growth†

• 85% less breakage†

†Based on a 90-day consumer study of participants who took Dynamic Hair Energy daily.

Our men’s group reported: 

• 94% thicker, fuller-looking hair†

• 100% less breakage†

• 94% new hair growth†

• 85% reduced shedding†

†Based on a 90-day consumer study of participants who took Dynamic Hair Energy daily.

At the 90-day mark, we expected participants to talk about their hair. Many also wanted to talk about how they felt.

Thinning hair is rarely just a hair problem. It affects how you feel in the mirror, how long you spend styling, and whether you want to be in the photo. So when your hair starts to feel like your own again, the benefits often go further.

Here's what our cohort shared.

• More everyday confidence. Women felt better about their hair in the mirror, in photos, and while styling, and that boost carried through their day.†

• Easier styling. Stronger, more manageable hair made it easier to style, hold volume, and try new looks.†

• Healthier-looking hair. Hair looked shinier, smoother, and more vibrant.†

• Stronger nails. Many women were surprised to find their nails less brittle and healthier-looking.†

• Confidence and presence. Men felt more confident at work, in social settings, and in daily interactions.†

• Motivation to stay consistent. Seeing results kept them on track and, for some, inspired better habits around nutrition, sleep, and stress.†

• Stronger nails. Several men noticed less nail breakage and healthier-looking nails.†

Participants weren't looking for dramatic makeovers. They wanted to feel like themselves again, and many said they did. Healthy hair is about more than how it looks. It's about how you feel and show up every day.

Here's what she had to say about the 90-day trial results: 

Thinning hair rarely has a single cause, so a formula that targets just one factor rarely does enough. Dynamic Hair Energy is built on four foundations of healthy hair growth:*

1. Follicle energy. Hair follicles are some of the most active cells in the body, and they need steady energy to keep producing hair.*

2. Hormonal and DHT balance. Shifting hormones and DHT, a byproduct of testosterone, are major drivers of thinning in both women and men.*

3. Follicle nutrition. Follicles depend on key nutrients to build strong, healthy strands.*

4. Scalp blood flow. Good circulation delivers oxygen and nutrients to the follicle.*

These hero ingredients in Dynamic Hair Energy do the heavy lifting:

• Yüth®

• Serevelle® Saw Palmetto

• CELLg8®

• EVNolMax™

Hair grows in cycles, and every strand on your head is at its own stage. Hair grows about half an inch per month, and changes at the follicle take time to show at the surface. That's why we built our study, and our recommended plan, around 90 days.

• Days 1–30: Nourish. Your follicles begin getting the nutrients and support they need. You may not see changes yet, and that's normal.*

• Days 31–60: Support. As the formula keeps working, many people notice less shedding and breakage and stronger-feeling strands.*

• Days 61–90: Grow. This is when fuller-looking hair and new growth typically become visible.*

Consistency matters most. Taking your 2 capsules every day gives your follicles steady support through every phase of the cycle.*
