Why Hair Falls and What's Actually Behind It
Losing 50 to 100 hairs a day is normal. Hair grows in cycles, and shedding at the end of the telogen (resting) phase is part of how the follicle renews itself. The problem is when the shedding rate increases, the regrowth rate slows, or the hair that grows back is progressively thinner. When that pattern is sustained, it becomes noticeable and concerning.
The Most Common Causes of Excess Hair Fall
Nutritional deficiencies: Iron deficiency is among the most frequent underlying causes of hair fall in Indian women. Zinc, biotin, and Vitamin D deficiencies also affect follicle function significantly. Hair is energetically expensive to grow, and when the body is nutritionally stressed, it deprioritizes hair in favour of essential organ function.
DHT sensitivity: Dihydrotestosterone (DHT) is a hormone derived from testosterone that binds to receptors in scalp hair follicles, gradually shrinking them over time. This process, called miniaturization, is the main mechanism behind androgenetic alopecia (pattern hair loss) in both men and women. Natural compounds like pumpkin seed extract and zinc have been researched for their potential to reduce DHT activity at the follicle level.
Chronic stress: Stress triggers a shift in follicles from the growth (anagen) phase to the resting (telogen) phase. This is called telogen effluvium and can cause significant diffuse shedding 2 to 3 months after a stressful period, which is why people often cannot immediately connect the timing.
Poor scalp circulation: Follicles need a steady supply of oxygen and nutrients through blood flow. Reduced scalp circulation can slow growth and weaken existing hair shafts over time.
Natural Ingredients with Research Support
Bhringraj: Used in Ayurveda for centuries as a primary herb for hair health. Research suggests Bhringraj may promote follicle growth and support scalp circulation.
Pumpkin Seed Extract: A 2014 randomized controlled trial found that pumpkin seed oil supplementation improved hair count by 40 percent in men with androgenetic alopecia after 24 weeks, compared to 10 percent in the placebo group. Its action is partly attributed to 5-alpha reductase inhibition, the same mechanism targeted by pharmaceutical DHT blockers.
L-Cysteine and L-Methionine: Sulfur-containing amino acids that are structural building blocks of keratin, the protein that makes up hair. Adequate intake may support hair shaft strength and thickness.
Hydrolyzed Collagen: Provides amino acids that may support the structural integrity of the matrix surrounding each follicle.
D-Biotin: One of the most researched nutrients for hair. Deficiency is linked to hair thinning, and people with true biotin deficiency often see meaningful improvement with supplementation.
Zinc Citrate: Critical for follicle cell proliferation and sebaceous gland function. Hair fall is one of the earliest and most consistent signs of zinc deficiency.
Amla and Vitamin C: Support collagen synthesis around follicles and may reduce oxidative damage to hair follicle cells.
Noni: Rich in antioxidants and has been traditionally used to support scalp health and hair vitality in several Asian systems of medicine.
What Takes Time
Hair grows at roughly 1 to 1.5 cm per month. Follicle health changes even more slowly. Nutritional interventions for hair typically require 3 to 6 months of consistent use before visible results are apparent. This is not a category where immediate results are realistic, and any product claiming otherwise is misrepresenting how hair biology works.
Purezen RootCause
RootCause combines Hydrolyzed Collagen, L-Methionine, L-Cysteine, Bhringraj, Pumpkin Seed Extract, Noni, Amla, Vitamin C, Zinc Citrate, D-Biotin, and Piperine. It is formulated for adults experiencing hair fall who want to address potential nutritional gaps and support follicle health from within. It works best alongside a protein-adequate diet and, where relevant, assessment of any underlying deficiencies with a doctor.
