What’s the difference between Women’s and Women’s Balance?

Our Women’s formula is generally best for women of childbearing age (18-44). It targets 6 root causes of hair thinning with 1 comprehensive formula. Women’s Balance is boosted with additional hormone- and aging- supportive ingredients like Maca, Astaxanthin, and extra Saw Palmetto that are helpful for addressing hair thinning in peri- and postmenopausal women (typically ages 45+ or those concerned with hormone imbalances).

Why are Hair Growth Duos not available with Nutrafol Postpartum?

Postpartum uses breastfeeding-friendly botanicals to address postnatal nutritional gaps and stress for better hair growth and wellness through whole-body recovery post-childbirth. This product was designed to support women postpartum without the need for a targeted booster. Some of the ingredients in our Hair Wellness Boosters have not been tested for safety in breastfeeding women.

What is a Hair Wellness Booster?

While our Hair Growth Nutraceuticals address all 6 root causes of hair thinning, some of us need added support for our most problematic root causes based on our current lifestyle. Our targeted boosters are complementary formulas to help personalize and focus your growth journey in areas you need it most. Hairbiotic is designed to provide microbiome support with pre- and probiotics that improve digestion and promote absorption of hair health nutrients.

Will Nutrafol products work for my hair type?

Nutrafol products were formulated to promote hair growth and hair wellness for all types of hair. While the characteristics of hair strands may vary by ethnicity, the underlying root causes that affect hair follicles can affect all people equally.

In a recent clinical study, we examined the effectiveness of Nutrafol in African American, Asian, Hispanic, and non-Hispanic men and women. All ethnicities saw less shedding after 2 months and improved thickness, growth rate, scalp coverage, and shine after 6 months of taking our Hair Growth Nutraceuticals.

When can I expect to see results?

In our clinical studies, women showed results in 3-6 months. Results may vary.

1-3 Months

Hair strengthens from within. Notice better gut health like improved digestion and regularity. Look for shinier hair with less shedding and breakage.

3-6 Months

You may notice improvement in fullness and volume.

6+ Months

Experience visible changes like faster-growing hair that’s thicker and stronger.

Will I grow hair on other parts of my body?

No. Facial and body hair are triggered by different factors than the hair on our head. Saw Palmetto in our hair growth nutraceutical helps combat DHT, which may actually prevent facial hair growth.

How do I know if I need the Gut Microbiome Hair Growth Duo?

You know your body best—but, if in addition to thinning hair, you are experiencing brittle, dry or oily hair, fatigue, bloating, gas, and digestive complaints, this combo could be for you

Why can’t I buy Hair Wellness Boosters separately?

Our Hair Wellness Boosters don’t grow hair on their own! They are hyper-focused on balancing one of your key root causes of hair thinning to unlock the power of your Hair Growth Nutraceutical. Hairbiotic promotes hair wellness with probiotic strains that support nutrient absorption and gut health as it relates to hair.
