If you’re longing for thicker, healthier hair, say no more. The journey can feel like a never-ending cycle of trying new products, switching up routines, and still facing frustration. According to trichologist Dr Rekha Yadav though, understanding the science behind hair growth and thickness is key to achieving real results. Let's break down what actually determines hair thickness, how to enhance it, and which treatments genuinely work.
What Determines Natural Hair Thickness?
Can We Improve Hair Thickness?
Unfortunately, your hair strand cannot be thickened, but you can improve your hair density with a holistic approach. Dr Yadav emphasises that a combination of internal and external therapies is essential:
The Hair Growth Cycle's Impact
Hair goes through three phases:
- Anagen (growth phase): Lasts 2-6 years and determines hair length.
- Catagen (transition phase): Hair stops growing and detaches from the blood supply.
- Telogen (resting phase): Old hair sheds to make way for new growth.
Is Hair Miniaturisation Reversible?
Hair miniaturisation is when hair strands become thinner and weaker due to genetics, hormonal imbalances, or lifestyle factors. While severely miniaturised hair follicles may not regenerate, dormant ones can be revived with the right interventions. Dr Yadav suggests treatments like mesotherapy, PRP (Platelet-Rich Plasma), GFC (Growth Factor Concentrate), and exosome therapies to strengthen follicles and reduce hair loss.
Nutrition & Lifestyle’s Role In Hair Thickness
Which Nutrients Are Essential?
Dr Yadav insists that deficiencies in key vitamins and minerals can lead to hair thinning. Some crucial nutrients include:
- Iron & Ferritin: Essential for oxygen supply to hair follicles.
- Vitamin B12 & D3: Prevents premature shedding and strengthens strands.
- Zinc & Copper: Regulates hair follicle function.
- Selenium: Supports thyroid health, which directly impacts hair growth.
- Omega 3, 6 & 9: Reduces inflammation and nourishes the scalp.
- Protein: Hair is 90 per cent keratin, so a protein-rich diet is vital.
Scalp Health & Hair Thickness
A healthy scalp is crucial for thick hair. Product buildup, fungal infections, and poor hygiene can lead to inflammation, weakening the hair follicles. Using the right shampoo for your scalp type is key, and Dr Yadav advises against baby shampoos unless suitable for your scalp condition.
Hair thickness is predominantly in your genes. However, your lifestyle, nutrition, and the right treatments can make a huge difference to the appearance of your hair. Dr Yadav’s advice highlights the importance of treating hair holistically rather than just relying on external applications. Whether through dietary adjustments, stress management, or targeted treatments, you can improve your overall hair quality.
