Hair Care & Scalp Health Education
Understanding the biological hair growth cycle, evidence-based micronutrients, and recognizing when hair shedding requires medical evaluation.
The Three Phases of Hair Growth
Active growth phase lasting 2 to 7 years. About 85–90% of your scalp hairs are in anagen at any given time, synthesizing keratin.
Brief transitional regression lasting 2 to 3 weeks. The follicle shrinks and detaches from the dermal blood supply.
Resting phase lasting 2 to 4 months. Shedding 50–100 hairs daily is completely normal physiological turnover before the cycle restarts.
Evidence-Backed Nutrition for Follicles
- • Serum Ferritin (Iron): Iron deficiency is one of the most common reversible drivers of diffuse telogen effluvium, especially in women and vegetarians. Include green leafy vegetables and lentils paired with Vitamin C.
- • Adequate Dietary Protein: Hair shafts are composed of 90% keratin protein. Ensure daily intake of dals, paneer, eggs, seeds, and nuts.
- • Zinc & Vitamin D: Crucial cellular cofactors in follicular cycling and immune regulation.
Gentle Scalp Care Practices
- • Wash Frequency: Wash your scalp when it feels oily or sweaty. Allowing sebum and Malassezia yeast buildup worsens dandruff and inflammation.
- • Traction Prevention: Avoid habitually tight ponytails, buns, or braids which can cause irreversible traction alopecia.
- • Thermal Protection: Minimize direct high-heat blow drying and aggressive mechanical rubbing with abrasive towels.
When to Seek Dermatological Consultation
Consult a board-certified dermatologist if you experience: sudden coin-shaped smooth bald patches (Alopecia Areata), scalp burning, redness or scarring, loss of eyebrows/eyelashes, or rapid diffuse hair shedding persisting longer than 3–4 months. Self-treating with unregulated online oils often delays effective medical intervention.
