Thinning hair has multiple root causes.
Research shows that several underlying factors within the body can impact the hair growth cycle. That's why we developed a multi-targeted approach that addresses the key root causes of hair thinning.

Growth

Transition
03
Rest
Hormones
DHT sensitivity can be caused by genetics, stress, poor diet, and toxins.
Stress
Physical or emotional stress like giving birth or a demanding job.
Lifestyle
Refers to your surroundings, the products you use, and foods that you eat.

Metabolism
Influences how hair follicles receive nutrients from the body.
Nutrition
Nutrient gaps that can result from a 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.

Signs of aging
Hair thinning, coarse texture, weakened hair that grows slowly, thin skin, fine lines, and wrinkles can all be signs of aging.
How it affects your hair
The production of collagen and elastin in the scalp slows as we age. The structural breakdown prevents key components, like blood vessels, lipids, melanocytes, and nerve endings from protecting, hydrating, and replenishing key nutrients needed for healthy hair growth. With the loss of collagen and elastin, the scalp is no longer as strong and able to hold on to hair. As a result, hair cannot grow as long and becomes 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.

Signs of stress
Shedding or thinning hair, not just at the hairline or part. You also may feel like you 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 out of the hair growth phase, accelerating the time it takes for hair to shed. Over time, stress can also impact hormones and nutrient absorption needed for hair growth.
How we target it
Ashwagandha 10% withanolides is one way Nutrafol’s Hair Growth Nutraceuticals address occasional stress. Ashwagandha is an adaptogen that helps balance stress hormones in the body.

Signs of hormonal effects
Hormones biologically affect hair growth in men and women differently. Men may show changes at the hairline and overall thinning, while women often see part line changes. Women may also experience unwanted facial hair growth, and irregular periods due to perimenopause.
How it affects your hair
Changes in hormones due to aging can make your body more susceptible to DHT hormone. DHT hormone causes hair follicles to shrink (miniaturize) and can shorten the hair growth cycle.
How we target it
Saw Palmetto is one way Nutrafol’s Hair Growth Nutraceuticals support normal hormonal changes with aging that impact hair. Saw Palmetto helps lower the conversion of testosterone to follicle-shrinking DHT hormone to promote hair growth.

Signs of lifestyle effects
Damaged hair that is weak, brittle, and breaking.
How it affects your hair
Lifestyle refers to your surroundings, the products you use, and the foods you eat, which can weaken the health of the hair follicle.
How we target it
Tocotrienol Complex, a concentrated form of vitamin E, is one way Nutrafol’s Hair Growth Nutraceuticals provides antioxidant support against environmental stress to improve hair density.

Signs metabolism is playing a role
Breakage and hair that is having trouble growing can be a sign of metabolism's effect on hair. You can often see the effect of metabolism through age.
How it affects your hair
Your cellular metabolism receives nutrients and signals from the body to provide energy for your hair follicles to grow hair.
How we target it
Curcumin, standardized with 45% curcuminoids, is one way Nutrafol’s Hair Growth Nutraceuticals support metabolism. It is a robust ingredient with antioxidant activity that supports metabolic function and multiple root causes of hair thinning.

Signs of nutrient gaps
Brittle, dry hair or all over thinning can be signs of gaps in the body's nutrients that are needed to support healthy hair growth.
How it affects your hair
Key nutrients are needed to build hair and support a healthy hair growth cycle. As a micro-organ, our hair follicle is affected by nutrient deficiencies. This can be further impacted by stress or nutrient absorption from the gut microbiome.
How we target it
Marine Collagen Peptides, vitamins and minerals are some ways Nutrafol Hair Growth Nutraceuticals help provide the building blocks of strong hair fibers.
