Natural Hair Regrowth Experiment

Jun 8, 2025

Overview

A personal trainer describes his 16-week experiment to reverse hair thinning using dietary adjustments, supplements, and topical compounds, ultimately achieving noticeable regrowth without pharmaceutical interventions.

Background and Motivation

  • Began losing hair in his mid-20s, first at the crown, then at the hairline.
  • Experienced side effects from topical minoxidil and chose not to use finasteride due to potential risks.
  • Observed that hair loss is a significant stressor for men in the fitness industry.

Risks of Conventional Treatments

  • Finasteride, commonly used for hair loss, can cause sexual dysfunction, depression, and other side effects, sometimes persisting after discontinuation.
  • Government warnings highlight potential serious psychiatric and sexual side effects with finasteride.

Natural Approach and Research

  • Investigated multiple causes of hair loss beyond DHT, such as nutrient deficiencies, inflammation, oxidative stress, and gut health.
  • Consulted health community and reviewed academic research to identify promising natural ingredients and protocols.

Supplements and Topical Treatments Used

  • Utilized a regimen including Redensyl (for follicle stem cells), copper peptides (GHK-Cu, stimulates follicles and scalp health), niacinamide, and topical caffeine.
  • Applied beef tallow and castor oil for their nourishing and anti-inflammatory properties; found rosemary oil too greasy.
  • Additional oral supplements tried: bamboo extract (for silica), betaine HCL (for digestion), and biotin (vitamin B7 for keratin production).

Diet and Nutrition Adjustments

  • Regularly consumed liver and oysters for zinc and other nutrients, plus raw egg yolks and collagen shakes.
  • Increased intake of collagen and gelatine from organ meats, chicken skin, bone broth, and homemade jelly.
  • Avoided intermittent fasting and low-carb diets, citing research linking these diets to increased hair loss.

Exercise and Lifestyle Factors

  • Reduced physical and mental stress by limiting intense workouts and ensuring regular, moderate physical activity.
  • Maintained weight training three days per week and daily walking.

Ineffective Methods

  • Topical melatonin, minoxidil, and dermarolling were discontinued due to side effects or lack of results.

Results and Recommendations

  • Saw significant hair regrowth and reversal of thinning after 16 weeks on the regimen.
  • Suggests boosting gelatine intake and using caffeine, copper peptide, and Redensyl for those noticing hair thinning.
  • Acknowledges diet and exercise alone may not be as effective as supplement-based interventions but are still beneficial for overall health.

Recommendations / Advice

  • Investigate natural solutions early when noticing hair thinning.
  • Prioritize evidence-based ingredients and monitor for side effects.
  • Avoid restrictive diets linked to increased hair loss.
