Introduction:
Hair health is determined by scientific parameters that assess hair growth, scalp condition, and hair
fall severity. At Skin City, microscopic hair analysis involves dermatoscopic examination of the scalp
and an Anagen-Telogen ratio (A-T ratio) assessment using the pull test to evaluate overall hair health.
Understanding Hair Growth Phases
Hair undergoes a cyclical growth process, consisting of three primary stages:
Catagen Phase (Transitional Phase): A 2-4 week phase where hair prepares for rest.
Telogen Phase (Resting Phase): Lasts 3 months, where old hair falls out, making way for new growth.
The Terminal to Vellus (T:V) Hair Ratio
Terminal hairs are thicker, fully grown strands, while vellus hairs are thin, fine strands.
A normal T:V ratio falls between 4:1 and 7:1 in a healthy scalp.
A T:V ratio below 4:1 is often linked to androgenetic alopecia (pattern baldness).
Common Causes of Hair Loss
Hair loss varies by individual and is influenced by multiple factors:
1. Androgenetic Alopecia: Caused by Dihydrotestosterone (DHT) accumulation, leading to hair follicle shrinkage.
2. Hormonal Imbalances: Conditions like hypothyroidism can disrupt hair growth cycles.
3. Medical Conditions: Typhoid, viral infections, chemotherapy, major surgeries, and excess vitamin
A intake can trigger hair loss.
Nutritional Deficiencies: Lack of proteins, iron, and vitamins can lead to hair thinning.
Stress & Lifestyle: Severe emotional or physical stress can contribute to sudden hair fall.
Chemical & Heat Treatments: Frequent use of shampoos with harsh chemicals, dyes, styling gels, straightening, and perming can damage hair.
Understanding these factors is crucial for personalized hair loss treatment and scalp health management. A scientific hair diagnosis can help identify the root cause and create a customized treatment plan for optimal hair regrowth.
