While most people are aware of the harmful effects of sun exposure on skin, hair health is often overlooked. Dermatologists warn that prolonged exposure to harsh sunlight can leave hair dry, brittle, and more prone to damage.
As temperatures rise during the summer months, the impact of sun exposure on hair becomes more noticeable. Increased hair fall, dryness, frizz, and dullness are common concerns for many. According to Dr. Smriti Naswa Singh, Consultant Dermatologist and Cosmetic Dermatologist at Fortis Hospital, Mumbai, it’s essential to extend sun protection to your scalp and hair to maintain overall hair health.
How Does Sunlight Affect Hair?
“Just like your skin, your hair and scalp are exposed to ultraviolet (UV) radiation daily,” explains Dr. Singh. “Excessive sun exposure can damage the hair’s outermost layer, known as the cuticle, leading to weakened strands and increased breakage.”
The sun also strips away natural oils, which are essential for maintaining hair moisture and elasticity. This can result in rough texture, split ends, and frizz. Those with color-treated or chemically processed hair are particularly vulnerable, as UV rays can cause fading and intensify dryness.
Additionally, the summer heat increases perspiration, making the scalp oilier. This can clog pores, exacerbate dandruff, and cause itching—all of which contribute to hair thinning and increased hair fall.
Tips to Protect Hair from Sun Damage
To combat the harmful effects of sun exposure, Dr. Singh recommends the following dermatologist-approved strategies:
1. Cover Your Hair
Wearing a wide-brimmed hat, scarf, or using an umbrella can provide immediate physical protection from UV rays.
2. Use a Leave-In Conditioner with UV Protection
Opt for leave-in products specifically formulated to shield hair from sun damage. These help retain moisture and protect the hair shaft from environmental stressors.
3. Avoid Overwashing
Frequent washing can strip hair of its natural oils. Use a mild shampoo and rinse with cool water to soothe the scalp and preserve moisture.
4. Stay Hydrated and Eat Well
Hydration plays a critical role in hair health. Drinking sufficient water and eating fresh fruits and vegetables nourish hair from within and promote stronger strands.
5. Minimize Heat Styling
Limit the use of heat-based styling tools such as hair dryers, straighteners, and curling irons. Whenever possible, let your hair air-dry naturally.
6. Incorporate Weekly Oil Massages
A gentle scalp massage using oils like coconut, argan, or almond can enhance blood circulation, moisturize the scalp, and create a protective barrier against sun damage.
7. Choose the Right Hair Care Products
Select shampoos and conditioners that suit your hair type and avoid products with harsh chemicals—especially during the summer.
Dr. Singh also stresses the importance of scalp care. “If you experience symptoms such as itching, dandruff, or excessive hair shedding, don’t ignore them. A healthy scalp is foundational to healthy hair. Seek advice from a dermatologist if necessary.”
While the summer sun can pose a challenge to hair health, consistent care and simple preventive measures can go a long way. By following expert guidance, including Dr. Singh’s practical tips, individuals can enjoy the season while keeping their hair healthy, vibrant, and protected.
Remember, hair health requires both external protection and internal nourishment. Taking care of your hair during the summer is not just about aesthetics—it’s about overall well-being.
