Hair loss affects over half the population, with Androgenetic Alopecia (common hair loss) impacting more than 50% of men over 40 and 75% of women over 65. According to the American Hair Loss Association, 65% of American men experience hair loss by age 35, and 85% by age 50. Surprisingly, women make up 40% of all hair loss sufferers.
While the causes of hair loss vary, the good news is there are science-backed strategies to maintain healthy hair and reduce loss. Here are 10 methods, supported by research, to help prevent and address hair loss.
1. Eat a Nutrient-Rich Diet
A healthy, balanced diet fuels your body and promotes strong hair growth. A 2018 study found that diets high in raw vegetables and fresh herbs, similar to the Mediterranean diet, reduce the risk of androgenetic alopecia and slow its onset. Include foods like parsley, basil, and salad greens in your meals at least three times a week.

2. Quit Smoking
Smoking has been linked to premature graying and accelerated hair loss due to its damaging effects on hair cells. Quitting smoking not only benefits your overall health but also supports hair health.

3. Boost Protein Intake
Hair follicles are primarily made of protein, so insufficient protein can lead to hair loss. Ensure your diet includes adequate amounts of lean meat, fish, eggs, or plant-based protein sources to support hair health.
4. Limit Alcohol Consumption
Excessive alcohol intake has been linked to reduced hair growth. A 2013 study found that consuming more than four alcoholic drinks per week was associated with increased hair loss.

5. Avoid Hair-Pulling Hairstyles
Tight hairstyles such as braids, ponytails, and buns can damage hair strands over time. According to the American Academy of Dermatology, pulling hair too tightly can weaken the bond between hair and scalp.

6. Minimize Chemical Treatments
Bleaching, dyeing, and other chemical treatments strip the protective keratin layer from hair, making it brittle and prone to breakage. Limiting these treatments helps preserve your hair's strength and structure.

7. Reduce Heat Styling
High-heat styling tools, such as hairdryers and curling irons, dehydrate hair and weaken its structure. Use heat protection products, opt for air-drying, and stick to the lowest possible heat settings when styling.

8. Manage Stress Levels
Stress-induced hair loss, including telogen effluvium, alopecia areata, and trichotillomania, is caused by inflammation affecting hair follicles. Manage stress through meditation, exercise, or engaging in hobbies to maintain healthy hair growth.

9. Supplement with Essential Nutrients
Deficiencies in biotin, zinc, iron, omega-3 fatty acids, and other vitamins can lead to hair thinning and loss. A balanced diet or high-quality multivitamin supplements can help fill nutritional gaps, but always consult a healthcare provider before starting supplements.

10. Use Red Light Therapy for Hair Growth
Red Light Therapy (RLT) uses red and near-infrared light to stimulate mitochondria in hair follicle cells, boosting energy production and promoting hair growth.
- How it works: RLT stimulates ATP production in the mitochondria, increasing cellular energy, collagen production, and microcirculation to the scalp. These effects encourage new hair growth, repair damaged follicles, and reduce oxidative stress.
- Clinical evidence: A 2019 meta-analysis of 11 trials found that red light therapy significantly increased hair density and improved hair growth for both men and women. Other studies confirm its safety and effectiveness for treating androgenetic alopecia (AGA).

How to Use RLT for Hair Growth
- Device: A portable LED panel like the Model 1+2 is ideal for targeted scalp treatments.
- Duration: Optimal exposure is 17 minutes per session.
- Distance: Position the device about 1 inch away from the scalp.
- Wavelength: Red light at 660nm is most effective for stimulating hair follicles.
