Is Nutrafol suitable for everyone?
Is Nutrafol suitable for everyone?
Not only is Nutrafol suitable for most people, but our hair growth supplements are specifically formulated to meet you where you are in life. We have 5 Nutraceutical formulas that are tailored to the bio-specific needs of men and women throughout all life stages: Women's, Women’s Vegan, Postpartum for the first year after childbirth or while breastfeeding, Women's Balance for peri- and postmenopause, and Men's.
Please note: We do not recommend Nutrafol to anyone under the age of 18. Also, while we have no reason to believe it's harmful, there have not been enough studies for us to say Nutrafol is suitable during pregnancy—so we recommend skipping it while pregnant or trying to conceive and sticking with Nutrafol Postpartum while breastfeeding. If you have a medical condition, or are taking medications (especially anticoagulant and blood-thinning drugs), please consult with your physician before taking Nutrafol.
What is the difference between Nutrafol's Hair Growth Nutraceuticals?
What is the difference between Nutrafol's Hair Growth Nutraceuticals?
Our Hair Growth Nutraceuticals are clinically effective and physician-formulated to the bio-specific needs of men and women through all life stages and lifestyles.*The key root causes of thinning hair affect men and women differently and can change over time—so we created multiple formulas to give your hair exactly what it needs, when it needs it most.
Women’s formula focuses on addressing the key root causes of hair thinning for women 18-44 years old when stress, lifestyle habits, and nutrition play a heightened role in hair health.
Women’s Vegan is formulated for women 18-44 with the key root causes of thinning focusing on stress and lifestyle habits, plus it is optimized to support plant-based diet’s nutrition and absorption of nutrients in the body that affect hair health.
Women’s Balance is formulated for women 45+ to support the key root causes of hair thinning for women, such as stress, with optimized support for hormonal changes, such as menopause, that affect hair health.
Postpartum is OBGYN-formulated to address the key root causes of hair thinning and shedding for women within the first year of giving birth and through the time they are breastfeeding, such as the physical and emotional stress, hormonal changes, and nutritional support.
Men’s formula multi-targets the key root causes of thinning for men 18+, such as stress and poor nutrition, with optimized support of hair growth-inhibiting DHT hormone, without compromising sexual performance.
Will Nutrafol work for my hair type?
Will Nutrafol work for my hair type?
Nutrafol was formulated to promote hair growth 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 two months and improved thickness, growth rate, scalp coverage, and shine after six months.
When can I expect to see results?
When can I expect to see results?
Everyone's experience is different, but in our clinical studies, women showed results in 3-6 months. It's important to remember that healthy hair growth takes time—and of course, consistency is key. If you take Nutrafol daily, here's a snapshot of what you're likely to experience:
1-3 months:Strengthen hair from within. 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 with more scalp coverage.
Commitment to Nutrafol has whole-body rewards, too. Our ingredients are shown to promote more restful sleep, less stress, better mood, and clearer skin. A little something we call side benefits.
