Forget the beach waves, your hair tends to feel greasy and limp even on the days you wash it. This tricky hair concern happens due to several reasons.

So why wait? Here's all you need to know to beat the heat in style.

Greasy Scalp

Why Does Your Scalp Get Greasy in Summer?

1. Natural Oils

Your scalp produces natural oils or sebum, which are essential to regulate the moisture balance in your hair. Hot and humid weather makes your sebaceous glands overactive and leads to excess oil production, leaving your scalp greasy and your hair looking flat.

2. Sweat

It's common knowledge that you sweat more in summer. Problem occurs when this sweat mixes with oil and dirt, creating buildup on your scalp. This can make your hair feel sticky, weighed down, and uncomfortable. It can even clog your hair follicles and cause dandruff. This is why using a shampoo for greasy scalp is crucial during summer.

3. Overwashing

Washing your hair too often is a vicious cycle. If you wash your hair too frequently, it may go dry. Then, your scalp compensates for it by producing even more oil. Swimming pool runs, beach days, too much dry shampoo, or simply humidity can throw you into this habit. But remember, overwashing simply makes your problems worse.

4. Heavy products

Some shampoos meant for greasy hair can be too strong. This can leave your mid-lengths and ends dry. As a result, you turn to heavy conditioners or moisturisers to bring back hydration and make your hair look limp in the process. Choose the right shampoos for greasy scalps to begin with to reset your hair washing routine.

5. Dust and Pollution

Summer can be dusty. The pollutants and particles of dust can settle on your scalp due to its greasiness. This can make your hair feel unclean even if you just washed it. It's a great practise to secure your hair with scarves and protective hairstyles before hitting the road in the summer.

6. Diet

Summers are for vacations, and vacations are a good time to let go. Unfortunately, all the processed foods and sugar can trigger oil production in certain cases. Making sure your body is well-nourished and hydrated is crucial for summer hair care.

How to Manage a Greasy Scalp in Summer

Tip 1: Use a shampoo for greasy hair

Using oil-control shampoos is a healthy practise in general, if you have an oily scalp. However, it becomes more crucial in the summers when sweat and humidity are at an all-time high. Look for a good shampoo that helps remove excess oil and keeps your scalp fresh.

This shampoo for a greasy scalp delivers a 3% concentrated AHA formula in a lightweight gel texture, giving you clean, fresh hair while accelerating your scalp's cell development process.

Tip 2: Schedule your Hair Washes

Washing your hair everyday may get tempting in summers. However, creating a schedule and staggering your hair routine helps you control this urge while caring for your hair. use a shampoo for greasy scalp 2-3 times a week to regulate oil production and keep your scalp balanced.

Tip 3: Keep your scalp hydrated

Summer heat and washes can dehydrate your lengths and a dry scalp can trigger more sebum production. But oiling can make your hair feel too sticky in summers. So, trade the heavy products with something better like the Anti-Discomfort Intense Soother Treatment to keep your scalp moisturised, soothed, and cleansed all at once.

Tip 4: Use cool to lukewarm water

Hot water strips away natural oils, making your scalp produce even more. Stick to lukewarm or cool water to keep oil production in check.

Tip 5: Choose Lightweight Hair Products

Heavy creams or serums might be good for your hair lengths, but for your scalp, switch to non-greasy, lightweight conditioners and styling products to prevent product build-up. Avoid heavy creams or serums that can cause build up on your lengths. 

By making small changes to your hair care routine and using the right products, you can keep your scalp fresh and oil-free all summer long. Choose the right shampoo for a greasy scalp to maintain healthy, clean hair that feels fresh even in the heat.
