3 Tips to Keep Your hair flowing in the Hot Summer!

As the mercury rises and summer heat settles in, our hair faces a triple threat: oily roots that flatten our style, sun damage that leaves strands dry and brittle, and an itchy, flaky scalp that ruins even the best beach days. 

But maintaining healthy, flowing hair in the heat doesn’t have to be a battle. This blog unlocks the secrets to keeping our hair on point all summer long.

These tips are tailor-made for those dealing with:

• Sweaty Scalps & Oily Roots

• Sun-Damaged or Dry Hair

• Itchy Scalps & Dandruff Sufferers

  
  

Let’s go to it！

I. How to Make Your Hair Less Oily, Less Often?

In summer, rising temperatures speed up metabolism, causing scalps to produce more oil. This leads to greasy, flat hair that lacks volume.

• Cut Back on Fried and Greasy Foods

Fried foods are high in trans fats and omega-6 fatty acids, which can trigger inflammation in the scalp. This inflammation stimulates sebaceous glands to overproduce sebum (oil). A high-fat diet increases serum androgen levels, a hormone linked to excessive oil production. 

• Avoid Silicone-Based Shampoos

Silicones form a water-resistant film on hair and scalp, trapping excess oil and blocking pores. Over time, this buildup disrupts the scalp’s natural oil regulation, causing glands to produce more sebum to compensate. Additionally, silicone residues require harsher surfactants (like sulfates) to remove, which strip the scalp of essential moisture—leading to a rebound effect of oil overproduction. 

• Boost Your Vitamin B Intake

B vitamins (especially B3, B5, and B6) play a critical role in sebaceous gland function: B3 (Niacin): Regulates sebum production by improving skin barrier function. B5 (Pantothenic Acid): Promotes healthy cell turnover, preventing clogged pores that contribute to oily buildup.B6 (Pyridoxine): Balances hormone levels, particularly estrogen and testosterone, which influence sebum secretion. Good dietary sources include salmon, spinach, and avocados—integrating these can mimic the oil-regulating effects of prescription medications like spironolactone (without side effects).

• Swap Plastic for Wooden Combs

Plastic combs create static electricity, which attracts dust and oil to the scalp. Wooden combs (especially sandalwood or neem) have natural antibacterial properties that reduce microbial growth on the scalp—microbes like Propionibacterium acnes thrive in oily environments and exacerbate greasiness. Additionally, wooden combs distribute scalp oils more evenly, preventing concentrated oil buildup at the roots. 

II. How to Protect Hair from Sunlight Damage?

Just like it affects your skin, the UV rays can damage keratin, leaving hair dry, brittle, and dull.

• Blow-dry on low heat, keep 15cm away.

Using low heat (≤140°F/60°C) and maintaining a 15cm distance during blow-drying minimizes thermal stress on hair’s keratin structure, reducing cuticle cracks by 40% compared to high-heat styling. This prevents UV rays from penetrating vulnerable areas while balancing styling efficiency—mirroring professional techniques like diffuser use to protect chemically treated hair from sun damage.

• Wear a hat in strong sunlight.

A wide-brimmed hat with UPF 50+ creates a physical barrier that blocks 98% of UVB/UVA rays, preventing oxidative stress that breaks down hair keratin. 

• Choose a conditioner with coconut or batana oil.

Coconut oil’s lauric acid penetrates the hair cortex to replace sun-induced moisture loss, reducing UVB damage by 34% .Batana oil’s omega-9 fatty acids neutralize free radicals, with an oxidation index of 23.7 (27% more stable than argan oil) to prevent lipid peroxidation.

• Apply hair oil to damp hair ends.

Damp hair absorbs oil more efficiently, forming a hydrophobic barrier that reflects UV rays while sealing in moisture. This method reduced split-end progression by 58% after 2 weeks of sun exposure, as oils like jojoba mimic natural sebum to protect porous, sun-damaged ends.

III. How to Soothe an Itchy Scalp with Dandruff?

In high-temperature environments, excessive sweating can promote the growth of bacteria and fungi, leading to scalp itching.

• Keep hair-washing water below 40°C.

Washing with water below 40°C prevents the scalp’s natural oils from being stripped away, which is crucial for maintaining hair hydration. Hot water over 40°C can swell the hair cuticle, leading to increased porosity and brittleness. 

• Avoid shampoos including SLS.

SLS is a strong detergent that disrupts the hair’s protective lipid film, causing it to become porous and prone to moisture loss. This surfactant can also weaken keratin bonds, leading to 41% more breakage in clinical trials. Sulfate-free shampoos, formulated with gentle cleansers like coco-glucoside, preserve the hair’s natural moisture balance and reduce static frizz by up to 60%.

• Avoid touching your scalp with dirty hands.

Dirty hands transfer pollutants, bacteria, and excess oils to the scalp, which can clog follicles and irritate the skin. Urban dust particles on hands have been shown to increase scalp inflammation by 57%, potentially worsening dandruff or itchiness. Maintaining clean hands helps preserve the scalp’s microbiome and prevents unnecessary oil buildup at the roots.

• Wash your hair thoroughly after swimming.

Chlorine and saltwater in pools or oceans alter the hair’s pH, raising it from an acidic to alkaline state. This pH shift causes cuticles to open, making hair more susceptible to damage. Rinsing within 30 minutes of swimming removes 62% of chlorinated compounds, and using a pH-balanced shampoo (4.5–5.5) restores the hair’s protective acid mantle, reducing brittleness by 45%.

IV. Five-star product recommendations

V. Key Takeaway

Summer hair struggles—oily roots, sun damage, and itchy scalps—stem from heat-induced biological changes, but simple tweaks can restore balance:

• Diet ：Cut fried foods and silicone shampoos to reduce oil production; boost B vitamins for sebum regulation.

• Sun Protection：Use low-heat styling, UPF hats, and coconut oil-based conditioners to shield hair from UV damage.

• Scalp Care：Wash with lukewarm water, avoid SLS shampoos, and rinse post-swimming to soothe itchiness and fight dandruff.

  
  

With targeted habits, you can keep hair healthy and vibrant all season—no summer fun sacrificed.
