Knowing your hair type helps you:
Choose the right shampoo and conditioner.

Aging
Hair often becomes thinner with age.
Heat Styling
Frequent heat exposure can temporarily change curl patterns.
What Does Research Say About Hair Types?
Quick Answer
Scientific studies show that hair shape varies according to follicle structure and genetics.
According to research published in the International Journal of Trichology, curly hair has an elliptical follicle, while straight hair typically grows from round follicles.
Another study from the National Institutes of Health (NIH) found that curl pattern affects moisture distribution and mechanical strength.
Statistics
The average human scalp contains approximately 100,000 hair follicles.
Hair grows about 0.5 inches (1.25 cm) per month, according to the American Academy of Dermatology.
Curly and coily hair are more prone to dryness because natural oils do not travel easily down the strands.
Around 65% of women have naturally textured hair, according to beauty industry market reports.
What Do Experts Say About the Hair Classification System?
Quick Answer
Experts agree that understanding hair types helps people create healthier routines.
"Hair texture and curl pattern significantly influence how hair responds to products and styling practices."
— Dr. Wilma Bergfeld, dermatologist and hair specialist at Cleveland Clinic.
She emphasizes that personalized care based on hair texture can minimize damage and improve hair health.
