5 Ways Your Hair Changes After 40—and How to Care for It as You Age
Key Hair Changes After 40
- Hair Becomes Sparser
- Hormonal shifts during perimenopause (especially declining estrogen) can lead to hair thinning, especially around the part.
- This is often due to increased sensitivity to testosterone, leading to shorter hair growth cycles and more shedding.
- Hair Gets Finer
- Shrinking hair follicles due to hormonal changes result in finer strands.
- Genetics play a major role in how much thinning occurs.
- Texture Becomes Drier and More Brittle
- Years of styling, chemical treatments, and environmental exposure weaken hair.
- Reduced oil production from the scalp contributes to dryness.
- Loss of Shine
- Less natural oil and cumulative damage from heat and chemicals can dull hair’s natural luster.
- More Gray Hairs Appear
- Aging reduces melanin production in hair follicles.
- Genetics and stress can accelerate graying.
Hair Care Tips for Your 40s and Beyond
- Gentle Cleansing: Use sulfate-free, hydrating shampoos; alternate with dandruff shampoos if needed.
- Deep Conditioning: Look for products with keratin, amino acids, and plant proteins to strengthen hair.
- Minimize Damage: Reduce heat styling and chemical treatments; always use heat protectants.
- Medical Checkups: Hair changes can signal underlying health issues like thyroid problems or nutrient deficiencies.
- Professional Help: Dermatologists can diagnose and treat hair loss with medications like minoxidil or procedures like PRP (platelet-rich plasma) therapy.
