The sunshine and warmth of summer bring countless joys to Canadians after our long winters. Unfortunately, they can also bring an unwelcome gift: excessively oily hair. If you find your scalp becoming a grease factory during the warmer months, you’re not alone. At Head Spa Toronto, we understand the frustration of hair that feels dirty hours after washing and the constant battle against flat, limp strands when the temperature rises.
The good news? With the right approach and specialized treatments, summer can actually be a season of beautiful, balanced hair. This comprehensive guide explores why summer exacerbates oily scalp conditions and outlines effective professional and at-home treatments to keep your locks fresh and volumized all season long.
Why Summer Makes Your Hair Oilier
Before diving into solutions, it’s important to understand why summer intensifies oily scalp issues:
The Science of Summer Sebum
In warmer weather, your body temperature rises, which makes your sebaceous glands overactive and triggers them to produce more sebum. This natural oil is meant to protect your scalp and hair, but when produced in excess, it creates that heavy, greasy feeling we all dread.
Sweating compounds the problem by helping oil slide down the hair shaft more easily, covering more of the hair instead of remaining closer to the scalp. This combination of increased oil production and sweat creates the perfect storm for persistently greasy hair.
Environmental Factors
Summer brings additional challenges that affect scalp health:
- Increased humidity, which can activate oil glands
- Higher exposure to pollution that adheres to oil on the scalp
- UV radiation that alters the scalp’s microbiome
- Salt and chlorine exposure from swimming
- More frequent hat-wearing, which increases scalp temperature
These factors don’t just make existing oil more noticeable—they actually stimulate your scalp to produce more oil as a protective response.
Professional Scalp Treatments for Summer Oil Control
At Head Spa Toronto, we’ve developed specialized summer treatments designed specifically to address seasonal oiliness:
1. Clarifying Scalp Detox Treatment
Our signature summer detox treatment provides deep cleansing without stripping the scalp of essential moisture:
- Clay-based therapy: Natural clays absorb excess oil while balancing the scalp’s microbiome
- Enzymatic exfoliation: Gently removes dead skin cells and oil buildup without harsh scrubbing
- pH balancing components: Restores optimal scalp pH to regulate oil production
- Cooling essential oils: Mint and eucalyptus provide a refreshing sensation while naturally regulating sebum
This 45-minute treatment is recommended bi-weekly during summer months for those with persistently oily hair. Clients report hair staying fresh up to twice as long after this specialized detox.
2. Microbiome Rebalancing Protocol
Recent research reveals that an imbalanced scalp microbiome can trigger excessive oil production. Our specialized treatment addresses this root cause:
- Probiotic scalp therapy: Introduces beneficial bacteria to create a balanced microbiome
- Prebiotic nourishment: Feeds healthy microorganisms while discouraging overgrowth of oil-stimulating bacteria
- Anti-inflammatory botanicals: Reduces scalp irritation that can trigger oil production
- Deep follicle purification: Removes bacterial buildup from within the follicles
Most clients notice significant improvements after 2-3 treatments, with cumulative benefits developing over time. This approach is particularly effective for those who’ve tried numerous products without lasting results.
3. Astringent Botanical Treatment
This treatment harnesses the power of natural plant compounds that have been scientifically proven to regulate sebum production:
- Witch hazel therapy: Natural astringent properties tighten pores and reduce oil secretion
- Green tea infusion: Rich in catechins that regulate sebum production
- Sage and rosemary essential oils: Traditional oil-balancing botanicals with modern scientific backing
- Apple cider vinegar pH treatment: Resets scalp pH to discourage overproduction of oil
The cooling sensation this treatment provides is particularly welcome during hot summer days, and the oil-controlling benefits typically last 7-10 days.
Home Care Essentials for Oily Summer Hair
Professional treatments provide deep, transformative results, but daily maintenance is crucial for ongoing oil control. Here’s what we recommend to clients at Head Spa Toronto:
Optimal Cleansing Routine
Finding the right washing frequency is critical in summer:
- Moderate frequency: For most people with oily hair, washing every other day during summer provides the best balance
- Tepid water temperature: Hot water stimulates oil production; cooler water helps control it
- Proper application technique: Apply shampoo directly to the scalp and massage gently with fingertips, not nails
- Thorough rinsing: Residual product can contribute to buildup and flat-looking hair
We recommend alternating between a gentle daily shampoo and a weekly clarifying formula to prevent product accumulation without drying out the scalp.
Strategic Conditioning
Many people with oily hair skip conditioner entirely, but this can actually worsen the problem by triggering the scalp to produce more oil. Instead:
- Apply conditioner from mid-lengths to ends only, avoiding the scalp entirely
- Choose lightweight formulas specifically designed for oily hair
- Consider leave-in treatments for ends while keeping roots product-free
- Use cool water for the final rinse to close the cuticle and reduce oil slide
This balanced approach protects your hair from summer damage while preventing the heavy, weighted-down feeling that comes from over-conditioning.
Scalp Tonics and Serums
Between washes, specialized scalp products can help control oil production:
- Mattifying tonics: Applied to the scalp after washing to reduce oil production throughout the day
- Astringent serums: Used on particularly oily areas to tighten pores
- Microbiome sprays: Maintain healthy bacterial balance on non-wash days
- Scalp sunscreen: Protects from UV damage without adding greasiness
These targeted treatments provide ongoing maintenance between professional treatments and regular washing.
Natural Remedies for Oily Summer Scalp
Traditional ingredients can be surprisingly effective for managing oily scalp, especially when incorporated into a consistent routine:
Apple Cider Vinegar Rinse
When properly diluted, an apple cider vinegar rinse can help remove product buildup, balance scalp pH, and reduce oil production. The recommended ratio is one tablespoon of ACV to one cup of cool water, applied after shampooing and left on for 5 minutes before rinsing.
Aloe Vera Treatments
The cooling and anti-inflammatory effects of aloe vera make it an excellent summer treatment for oily scalps. A weekly aloe vera scalp mask can soothe irritation, remove buildup, and provide natural hydration without heaviness.
Clay Masks
Natural clays like kaolin and bentonite are highly absorbent and can draw excess oil from the scalp. A bi-weekly clay mask application focused on the scalp rather than the hair lengths can significantly reduce oiliness without causing dryness.
Lifestyle Adjustments for Healthier Summer Hair
Beyond products and treatments, certain lifestyle habits can make a dramatic difference in controlling oily hair during summer:
Hands-Off Policy
One of the easiest ways to reduce greasiness is simply to touch your hair less. Our fingertips contain oil-producing glands, and each time you run your hands through your hair, you’re transferring more oil to your strands.
Brush Hygiene
Your hairbrush can be a repository for oil, product residue, and bacteria that get redeposited on your clean hair with each brushing. Washing brushes weekly with a gentle shampoo prevents this oil recycling process.
Dietary Considerations
What you eat can affect your scalp’s oil production. During summer, consider:
- Reducing dairy consumption, which can increase sebum production in some people
- Increasing zinc-rich foods like pumpkin seeds, which help regulate oil
- Staying well-hydrated to reduce the need for sebum protection
- Consuming omega-3 fatty acids for balanced oil production
These nutritional approaches complement external treatments for a holistic solution to oily hair.
Summer Hairstyling for Oily Hair
The right styling techniques can help manage the appearance of oil while you work on addressing the root causes:
Volume-Building Techniques
Oil tends to flatten hair, so counteract this with:
- Root-lifting products applied to clean, damp hair
- Strategic blow-drying with the head inverted
- Teasing or backcombing at the crown for additional lift
- Volumizing dry shampoo on days between washes
Protective Styles
Certain hairstyles can help minimize oil’s visual impact and prevent it from spreading:
- Braids that keep hair off the face and neck
- Top knots that concentrate oil at the roots where it’s less visible
- Half-up styles that showcase cleaner ends
- Textured styles that disguise oiliness better than sleek looks

Every person’s scalp changes with the seasons, which is why we recommend quarterly scalp analyses at Head Spa Toronto. Our summer assessment includes:
- Microscopic evaluation of sebum production levels
- Analysis of scalp microbiome health
- Assessment of follicle condition and potential buildup

This data-driven approach ensures you’re not just masking symptoms but addressing the specific causes of your summer oil production.
