New Hair Loss Index Reveals Hair Loss Risk in the U.S

According to recent studies and analyses of hair loss trends in the US, androgenetic alopecia (AGA) (also known as pattern baldness) remains the most prevalent type of loss, affecting 50 million men and 30 million women. 

Key Findings Include:

• Prevalence of AGA: 85% of men and 33% of women will experience some form of AGA in their lifetime.
• Age: Moderate to severe loss increases with age, affecting 25% of individuals aged 18-29, 41% of those 30-44, 54% of those 45-64, and 67% of those 65 and older.
• Gender differences: Women tend to report milder thinning (46.8% vs 34.1% in men), while men exhibit a higher prevalence of severe loss (12.5% vs 10.7%).
• Genetic predisposition: Genetic influence appears stronger in men for AGA (68%-74% vs 33%-48% in women), but female pattern loss is often more multifactorial, involving hormones, medical conditions, and stress.
• Factors influencing hair loss: Hormonal changes, stress, and a history of COVID-19 are significant predictors of hair loss, with postmenopausal and postpartum women at higher risk.

Hair loss, also known as alopecia, can be caused by a variety of factors, including genetics, hormonal changes, medical conditions, and stress. Hereditary hair loss (androgenetic alopecia) is a common cause, particularly male-pattern baldness and female-pattern hair loss. Other causes include autoimmune diseases like alopecia areata, where the body attacks hair follicles, and various medical conditions, such as thyroid disorders and skin infections. Stress, nutritional deficiencies, and even certain hairstyles can also contribute to hair loss. 

Here’s a more detailed breakdown:

1. Genetics:

• Hereditary hair loss (androgenetic alopecia): This is the most common type, characterized by a gradual thinning of hair, and is influenced by genes inherited from both parents. 
• Male-pattern baldness: Typically involves a receding hairline and thinning on the crown. 
• Female-pattern hair loss: Usually presents as a general thinning of hair, particularly on the top and crown of the head. 

2. Hormonal Changes:

• Pregnancy: Hormonal shifts during and after pregnancy can cause temporary hair shedding (telogen effluvium). 
• Childbirth: Similar to pregnancy, childbirth can trigger a period of increased hair shedding. 
• Menopause: Hormonal fluctuations during menopause can also lead to hair thinning. 
• Thyroid disorders: Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can affect hair growth and cause hair loss. 

3. Medical Conditions:

• Alopecia areata: An autoimmune disease that causes patchy hair loss on the scalp and other parts of the body. 
• Skin infections: Ringworm (tinea capitis) can cause hair loss on the scalp. 
• Lupus: An autoimmune disease that can affect various parts of the body, including the hair. 
• Certain cancers: Cancer treatments like chemotherapy and radiation can cause hair loss. 

4. Stress:

• Physical stress: Surgery, illness, or major injuries can trigger telogen effluvium. 
• Emotional stress: Significant life events or prolonged stress can also contribute to hair loss. 

5. Nutritional Deficiencies:

• Iron deficiency: Low iron levels can lead to hair shedding and thinning. 
• Protein deficiency: Insufficient protein intake can affect hair growth. 
• Vitamin deficiencies: Deficiencies in vitamin D, zinc, and other vitamins can impact hair health. 

6. Hairstyles and Hair Care:

• Traction alopecia: Tight hairstyles like braids, cornrows, and ponytails can pull on hair follicles and cause hair loss. 
• Harsh chemical treatments: Perms, relaxers, and excessive bleaching can damage hair and lead to breakage. 
• Heat styling: Frequent use of hot tools like hair dryers, straighteners, and curling irons can dry out and weaken hair. 

7. Medications:

• Chemotherapy drugs: These medications are known to cause significant hair loss. 
• Certain medications: Some drugs used to treat high blood pressure, depression, and other conditions can also contribute. 

8. Other Factors:

• Smoking: Smoking can restrict blood flow to the scalp, reducing nutrient delivery to hair follicles. 
• Excessive alcohol consumption: Heavy drinking can also negatively impact hair health. 
• Age: Hair naturally thins with age.

New Hair Loss Index Reveals States Leading U.S. in Hair Loss Risk

A new analysis has revealed which U.S. states are losing their hair the fastest and where residents are most concerned about hair thinning and male pattern baldness.

This research was conducted for Hair Loss Awareness Month during August 2025, and it combined three key metrics: smoking rates, stress scores, and online search behavior into a composite Hair Loss Index(HLI) Score (0-100) ranking all 50 states:

Key Findings

• West Virginia tops the HLI with a high smoking rate (21.2%) and elevated stress score (55.28).
• Nevada ranks second, showing the highest stress score among the top five (59.9) and strong search activity for loss solutions.
• Louisiana takes third place, followed by Tennessee and Mississippi, both of which combine above-average smoking and stress levels with notable online search interest.
• Other Southern and Midwestern states, including Arkansas, Alabama, Oklahoma, and Alaska, dominate the top 10, highlighting a regional concentration of risk factors.
• In contrast, states like Utah, Connecticut, and California rank lowest in smoking rates, which contributes to their generally healthier lifestyle patterns.

Spokesperson Insight

Dr. Michael Rabin, MD & CEO of Laser Cap Company, commented, “The statistics in our research point to a troubling correlation between smoking, stress, and hair loss in some U.S. states, notably in the Southern and Western regions. Such lifestyle habits, coupled with increasing search volume for hair loss solutions, indicating a rise in awareness about the problem.”

“Spotting hair loss early can actually make a big difference. Devices like Laser Cap, which is an FDA‑cleared, non‑invasive treatment, allow you to manage your hair health right from home, without surgery or side effects.”

“It’s great to see more people searching for hair loss solutions; however, prevention is still the key, especially in places where stress and smoking are common.”

“People living in high‑risk states like West Virginia need to look at the bigger picture when it comes to hair health. It isn’t just about genetics; stress, daily habits, and overall lifestyle play a big role. Understanding how these factors affect your hair is the first step in protecting it.”

Methodology

Google search volume for loss-related terms (alopecia, hair loss, hair regrowth, hair thinning, how to stop loss) normalized per 100,000 people using 2024 U.S. Census population estimates to ensure fair comparisons across states of varying sizes.

• Adult smoking prevalence (CDC BRFSS 2023 data)
• Stress scores (WalletHub’s 2024 “Most Stressed States” report)

Metrics were scaled to 0-100 using Min-Max scaling and weighted (Smoking 35%, Stress 35%, Search 30%). Kentucky and Pennsylvania lacked smoking data and were assigned the U.S. national average (12%) to maintain full rankings.
