Best Shampoo for Oily Hair in Summer – Banish Grease Easily

Greasy hair during summer? This is a common issue—heat, humidity, and excess production of oil can cause your hair to go from clean to greasy in no time. What should you know, and what is the way out?

Why Summer Makes Oily Hair Worse

Summer brings hotter weather and longer days—which means a tendency to sweat more, clogged product build-up, and the scalp doing some extra work. Hot weather increases oil production, especially if you’re already prone to greasy roots.

Too many times, however, individuals respond by over-washing. At first, washing every day might seem just fine, but it can actually backfire and throw your scalp off balance. What really happens is that when your hair loses its natural oils, your scalp starts to produce extra oils trying to bring a balance. This action can make your hair greasier than before.

What to Look for in a Summer Shampoo

Choosing a shampoo for oily hair in the summer means choosing one that removes excess oil while not robbing your scalp of its moisture. Don't pick rich moisturising formulas—those are not oil-controlling shampoos. Go for the following essential ingredients:

• Salicylic Acid – Exfoliates and reduces oil build-up

• Charcoal or Clay – Absorbs grease

• Tea Tree Oil – Clarifies and soothes the scalp naturally

• Citrus Extracts – Help in refreshing and degreasing roots

GK Hair pH+ Clarifying Shampoo stands out here. It removes product buildup and excess oil without stripping your hair. Unlike harsh clarifiers, it will correct the pH of your scalp without drying or flaking. And it's sulphate-free—a must for those who care about scalp health.

Daily vs Weekly Washing: What Works Best

During summer, it is easy to feel that you need to shampoo your hair daily. However, daily washing isn’t always ideal. The goal is to cleanse without triggering your scalp to produce more oil. A balanced strategy to manage an oily scalp? Try washing every two to three days with a clarifying shampoo—specifically designed to combat oily scalps. 

Keep the water warm and not a hot, steaming one. A lukewarm rinse preserves your scalp’s barrier while removing grime. Follow with a lightweight conditioner—applied only to the ends—to avoid weighing down your roots.

The Right Way to Apply Shampoo

The product matters, yes—however, it doesn’t only depend on the product. How you use the product matters a lot if you want a good result. You need to allow the product to sit for some minutes. The habit of not allowing the product to sit is common with people who lather and rinse quickly.
For deep cleansing:

• Wet hair thoroughly

• Apply shampoo directly to your roots
  

• Massage gently with fingertips (not nails!)
  

• Let it sit for 1–2 minutes

• Rinse thoroughly

• Once a week, wash your hair twice, especially after using styling products or you have been outdoors for a longer period.

Lifestyle Habits That Control Oil

Your shampoo is only part of the picture. Summer routines also affect oil levels. Take, for instance, tight hairstyles can trap heat and sweat on your scalp; try to loosen up a little whenever you can. Touching your hair too often is strongly advised against. When you do that, your fingers transfer oils to your roots, and you have more grease to deal with.

Instead of touching your hair too often, get a natural-bristle brush that is capable of moving oils from your scalp to the roots. You can be sure to have cleaner roots for a long time.

Use a boar bristle brush—GK Hair's Vent Brush makes a great substitute if your strands are prone to tangling.

Scalp maintenance is just as vital. Excess sebum production, according to the National Institute of Health (NIH), may lead to diseases like seborrheic dermatitis. Don't only focus on strands—your scalp needs maintenance too.

Shampooing Mistakes to Avoid

Even with a great product, there are bad habits that lower shampoo performance. Here's what not to do:

• Skipping Scalp Massage – Washing is all about contact, not lather.

• Using Too Much of the Product – A dime-sized amount is enough for most people.

• Mixing Products of any Random Brand – Different ingredients irritate your scalp.

• Not Clarifying – Especially in summer, it's not avoidable every week.

Avoid conditioners or masks for dry or damaged hair—too heavy for oily scalps. Instead, use targeted light-specific products like GK Hair Moisturising Conditioner, used mid-length to ends.
