Growing beyond conventional science.
Thinning hair has multiple root causes.
Research shows that several underlying factors that affect overall health can profoundly impact your hair and everyone’s combination of causes is different. Nutrafol targets key factors that can shorten the growth phase, delay new growth, and cause new hair to grow thinner.

Rest
Hormones
DHT sensitivity can be caused by genetics, stress, meds, poor diet, and toxins.
Stress
Short-term or chronic, physical or emotional stress like a surgery or demanding job.
Lifestyle
Refers to your surroundings, the products you use, and foods that you eat.

Metabolism
Influenced by inflammatory processes, high glycemic diet, and thyroid issues.
Nutrition
Nutrient deficiencies result from poor diet or a compromised gut microbiome.
Aging
The scalp loses collagen and elastin as you age, meaning it’s not strong enough to hold onto hair strands.
Identifying and targeting your hair growth obstacles.

By age 50, you’ll lose up to 30% of your collagen.
Signs of aging
Hair thinning, coarse texture, weakened hair that grows slowly, thin skin, fine lines and wrinkles, achy joints, and brittle bones can all be signs of aging.
How it affects your hair
The scalp loses collagen and elastin as you age. This structural breakdown prevents key components like blood vessels, lipids, melanocytes, and nerve endings from protecting, hydrating, and replenishing nutrients needed for hair growth. As a result, hair becomes shorter, weaker, and less pigmented.
How we target it
We use Marine Collagen Peptides to replenish key amino acids that build strong hair and provide hydration to the scalp, plus Vitamin D to reduce hair damage.

75% of Americans report increased feelings of stress in the past year (2019).1
Signs of stress
Excessive shedding or all-over thinning hair, not just at the hairline or part. You also may feel stressed or anxious, have trouble sleeping or waking up, or feel tired or wired throughout the day.
How it affects your hair
The stress hormone cortisol signals hair follicles to prematurely shift from growth to rest where the hair can no longer grow. Over time, stress can also disrupt our hormones and increase nutrient deficiencies needed for hair growth. Chronic stress can result from a demanding job, caretaking, toxic relationships, or poor sleep habits. Acute stress can be caused by events like a big move, a breakup, illness, or surgery.
How we target it
Sensoril® Ashwagandha. Nutrafol is the only hair supplement made with this innovative and clinically proven adaptogen that helps you build resistance to stress by balancing elevated cortisol.

Men have 40% more androgen receptors than women do, which is why male and female hair loss patterns tend to be different.
Signs of hormonal effects
In men, a receding hairline and thinning at the crown is common while women often see hairline changes or a widening part. Women may also experience acne, unwanted facial hair growth, and irregular periods.
How it affects your hair
Genetics, lifestyle, and age all increase the likelihood that DHT will affect hair follicles and cause thinning hair.
DHT (Dihydrotestosterone) is an androgen hormone that’s responsible for the development of male traits. It’s present in both men and, to a lesser extent, in women.
It’s also produced in the scalp and causes the hair follicle to slowly shrink
(a process called miniaturization) and eventually close entirely so that hair can no longer grow back.
While genetics and lifestyle factors play a major role in men’s hair thinning, hormonal changes from motherhood, menopause,
and stress are significant contributors to DHT imbalance in women.
DHT sensitivity can also be caused by aging, smoking, stress, medications, poor diet, and environmental toxins.
How we target it
Saw Palmetto is known to balance hormones and lower DHT in both men and women (without affecting testosterone levels or compromising sexual health in men like other hair growth products can). Maca is exclusively included in Women’s Balance to provide additional support for hormone health through life stages of perimenopause, menopause, and beyond.

An estimated 93% of Americans have traces of BPA (plastics) in their bodies.2
Signs of lifestyle effects
All-over thinning, weak and brittle hair, scalp itchiness or dryness, fatigue, food sensitivities, and a low immune system could be signs that environmental triggers are affecting your hair.
How it affects your hair
Lifestyle refers to your surroundings, the products you use, and the foods you eat, which can influence the health of the hair follicle. These expose you to heavy metals like mercury, pollution, cosmetic and household chemicals, plastics, UV rays, and extreme temperatures that can increase oxidative stress (an excess of free radicals in the body) and throw off antioxidant balance. If the body is unable to clear toxins quickly, antioxidants stores are depleted allowing oxidative stress to damage the hair follicle and disrupt normal hair follicle cycling. This can cause weak and thin hair. Physical damage from overstyling is also counted in your hair’s environment.
How we target it
Tocotrienol Complex and Astaxanthin both help reduce oxidative stress to promote scalp and hair health. (Astaxanthin is exclusive to Women’s Balance.)

Over 100 million Americans are living with blood sugar issues.
Signs metabolism is playing a role
All-over hair thinning, changes in texture or sebum production, aging, difficulty managing weight, or sensitivity to high carb meals can indicate poor metabolism is affecting your hair.
How it affects your hair
The hair follicle has 20 different types of cells that need energy for hair growth. Your cellular metabolism is what provides that energy for your follicles to grow hair. Aging, inflammatory processes, high glycemic diet, hormone imbalance, and thyroid imbalances can all lead to poor metabolism, which leaves your body with less energy to power healthy hair growth.
How we target it
Curcumin promotes a healthy inflammatory response to support cellular metabolism and Organic Kelp supports thyroid health. Both are essential for the energy your body needs to grow hair.

85% of adults show poor absorption of nutrients on our Hair Mineral Analysis.3
Signs of inadequate nutrition
All-over thinning, brittle hair, dryness, changes in sebum, fatigue, bloating, gas, and digestive complaints can be telltale signs of compromised nutrition.
How it affects your hair
Key nutrients from the diet help build hair fibers, texture, and support hair follicle health. Your hair is made up of a resilient protein called keratin, which gives hair its strength. Nutrient deficiencies can result from an inadequate diet. But even if you’re eating the right foods, factors like stress or poor absorption from a compromised microbiome can divert essential nutrients away from your follicles to more vital organs leaving less nourishment for growth. Poor microbiome health can result from recent use of antibiotics, aging, a diet low in whole foods or high in processed foods, or lack of exercise.
How we target it
Marine Collagen provides amino acids your body uses to build keratin and 10 supportive vitamins and minerals like biotin, vitamin D, iodine, zinc, and selenium, which provide nutrition for hair fiber construction to support stronger hair growth.

By age 50, you’ll lose up to 30% of your collagen.
