Here's why:
* Hair growth is determined by genetics and hormones. Straightening simply alters the hair's texture and shape, it doesn't affect the hair follicles where growth originates.
* Straightening can damage hair. Excessive heat styling can lead to dryness, breakage, and split ends, which might *appear* like slower growth as the hair is shorter.
What can affect hair growth:
* Nutrition: A balanced diet with plenty of protein and essential vitamins is crucial for healthy hair growth.
* Scalp health: A clean and healthy scalp promotes optimal growth.
* Stress levels: High stress can hinder hair growth.
* Hormonal changes: Fluctuations in hormones can also affect hair growth.
* Medical conditions: Certain conditions can cause hair loss or slowed growth.
If you're concerned about your hair growth, consult with a dermatologist or a hair specialist.
