Summer Hair Care: How Heat and Humidity Affect Scalp Health

Summertime brings sunshine and warmth, but it can also wreak havoc on your hair and scalp. Heat and humidity during the summer months can lead to a host of scalp issues like greasiness, irritation, and dandruff during summer. Establishing a proper summer hair routine is crucial to maintaining the health of your scalp and tresses. In this article, we'll explore how summer weather affects your scalp and share essential hair care summer tips to keep your scalp happy and healthy all season long.

How do heat & humidity affect scalp health?

High temperatures and humidity levels can significantly impact scalp health during the summer months. The heat stimulates the sebaceous glands on your scalp, leading to increased production of sebum (the natural oils that keep your scalp moisturised). While some sebum is essential for maintaining a healthy scalp, excess oil can clog hair follicles and create an ideal environment for bacteria and fungi to thrive. This can result in scalp irritation, itchiness, and even infections.

Humidity adds to the problem by increasing moisture levels on your scalp. The excess moisture can disrupt the delicate balance of your scalp's microbiome, allowing the overgrowth of yeast-like fungi such as Malassezia. This fungus feeds on the oils on your scalp and can cause inflammation, leading to issues like dandruff during summer. Taking proactive steps in your summer hair care regimen can help combat these issues.

Gender-specific scalp concerns

While both men and women can experience scalp issues during summer, there are some gender-specific concerns to keep in mind. Men, for instance, tend to have larger sebaceous glands and produce more sebum compared to women. This can make them more prone to developing an oily scalp and related issues like dandruff and scalp acne during the hot and humid months.

Women, on the other hand, often struggle with frizzy and unmanageable hair due to the high humidity levels. The moisture in the air can cause the hair cuticles to swell and lift, resulting in a rough, frizzy texture. This can be particularly challenging for women with naturally curly or wavy hair. Additionally, hormonal fluctuations during menstrual cycles can impact sebum production in women, exacerbating scalp oiliness and related concerns. Understanding these differences can help tailor your summer hair routine accordingly.

Summer hair care routine: Men vs. women

Here's a comparison of summer hair care routines for men and women:

Best products for summer scalp care

To keep your scalp healthy and dandruff-free during summer, consider incorporating these products into your summer hair routine:

• Clarifying shampoos: These deep-cleansing formulas help remove excess oil, sweat, and product buildup from your scalp, preventing clogged pores and irritation.
• Tea tree oil-based products: Tea tree oil has natural antifungal and antibacterial properties that can help control dandruff and soothe an itchy scalp.
• Scalp masks: Nourishing scalp masks containing ingredients like aloe vera and green tea can help restore moisture balance and calm inflammation.
• Dry shampoo: For those days when you don't have time to wash your hair, a good dry shampoo can help absorb excess oil and refresh your scalp between washes.

DIY remedies for scalp health

In addition to store-bought products, you can also try these simple DIY remedies to promote a healthy scalp during summer:

• Apple cider vinegar rinse: Mix equal parts water and apple cider vinegar and use it as a post-shampoo rinse to help balance your scalp's pH and control dandruff.
• Coconut oil massage: Gently massaging your scalp with coconut oil can help moisturise and soothe irritation. Leave it on for 30 minutes before shampooing.
• Aloe vera gel: Apply fresh aloe vera gel to your scalp and leave it on for 15-20 minutes before rinsing. Aloe vera has cooling and anti-inflammatory properties that can help calm an itchy, sunburnt scalp.

Lifestyle tips

Beyond your hair care routine, making a few lifestyle changes can also contribute to a healthier scalp during summer:

• Stay hydrated by drinking plenty of water throughout the day.
• Protect your scalp from direct sun exposure by wearing hats or using umbrellas when outdoors.
• Maintain a balanced diet rich in vitamins and minerals that support healthy hair growth, such as biotin, vitamin C, and iron.
• Manage stress levels through regular exercise, meditation, or other relaxation techniques, as stress can exacerbate scalp issues.
• Avoid excessive use of heat styling tools that can further dry out your scalp and damage your hair.

Taking care of your scalp during summer involves a combination of using the right products, adopting healthy hair habits, and protecting your scalp from harsh elements.

FAQs

Do men need to wash their hair more often?

Yes, men generally produce more sebum than women, so they may need to wash their hair more frequently during summer to control excess oiliness and prevent scalp irritation.

How can women prevent frizz?

Women can minimise frizz by using moisturising hair products, applying anti-frizz serums, and opting for protective hairstyles that keep hair away from humidity.

Is dandruff worse in summer?

Dandruff during summer can be more prevalent due to the increased humidity levels and scalp sweat, which create an ideal environment for dandruff-causing fungi to thrive.

Can sunscreen be used on the scalp?

There are specialised SPF products designed for use on the hair and scalp that provide sun protection without leaving residue.

Does sweating cause hair loss?

Sweating itself does not cause hair loss, but the salt in sweat can irritate your scalp and contribute to hair breakage if not washed off regularly.

What are the best haircuts for summer?

Short haircuts, pixie cuts, and styles that keep hair off the neck and face can help minimise scalp sweating and keep you feeling cooler during summer.

Are cold showers better for hair?

Cold water can help seal the hair cuticles, reducing frizz and making your hair appear smoother and shinier. However, both hot and cold water have benefits for hair health when used in moderation.
