Does Hair Grow Faster In Summer?

Does hair grow faster in summer? You must have heard this question from many people. But have you felt like this? And if hair grows faster in summer, do you know the reason behind this? Today I will tell you about all these things in detail.

And apart from this, I will tell you such things that will help to regrow your hair and make them healthy in summer. So let’s go ahead and discuss all these things.

The National Institute of Health conducted a “Seasonal Changes in Human Hair Growth” study in 1991, which helps support this idea. Although there hasn’t been a lot of research done on this subject, and NIH did this study decades ago, the data is still pretty clear—warmer weather affects our bodies and positively impacts hair growth.

It comes out from the overhead lines that human hair grows faster during the summer, but only by about 10% compared to hair growth during the winter months.

Do you know that it is not summer in itself which stimulates the process? Let’s see what could be the reason behind this.

What affects faster hair growth in summer?

Is this because of the humidity present in the atmosphere? Well, I don’t think that only humidity stimulates hair growth. Perhaps it’s due to increased blood circulation.

We tend to be more physically active in summer, which increases the efficiency of blood flow. Increased blood flow means more blood reaches the scalp, so increased nutrients to the scalp equal slightly faster hair growth.

Or the warmer weather boosts the supply of nutrients needed for keratin production. The production of this protein (essential for hair growth ) increases, and your locks grow faster.

Other factors that stimulate hair growth in summer

Healthy diet

A balanced diet plays a vital role in keeping healthy long hairs as it fulfills all the nourishment requirements of the follicles, resulting in the fastest hair growth.

Any deficiency of iron, vitamins, zinc, or protein will lead to hair fall & slow growth. We eat lots of fruits and veggies in summer that positively impact the hair’s growth, strength, and volume.

Lots of hydration

During the warmer months, we drink roughly two and a half liters of water a day, beneficial for our hair. Much like a plant needs water to grow, so does hair. Water is a key ingredient that supports vitamins, which contribute to your hair growth.

Drinking sufficient water supports hair growth from root to tip. It also helps prevent split ends and brittle hair and makes your scalp healthy.


Sweating from your scalp helps unclog your hair follicles, allowing room for new hair growth. And blood flow to your hair, and the sweat makes them look shinier than before.

But it is important to note that while sweating does open up your hair follicles to promote new hair growth, excessive or salty sweat build-up on your scalp is not suitable for your hair.

The salt content of the sweat will make your hair lifeless. So, it is essential to wash your hair after your workout, so any excess sweat isn’t sitting on your head for a long time.


Exercise can help hair grow because it increases blood flow and circulation throughout the body. An increase in blood flow means that more nutrients and oxygen are reaching the scalp, promoting fast hair growth.

A proven fact is that 35-40 minutes of moderate exercise every day rejuvenates the hair, leading to healthy growth.

We have already discussed whether hair grows faster in summer or not and the factors that affect hair growth in summer.

Now let’s see things that will promote your hair growth and make them healthy and shinier than ever before.

Intakes that promote hair growth faster

According to board-certified dermatologist Sharleen St. Surin-Lord, our bodies require a diet high in plant-based foods, fiber, antioxidants, and protein for optimal hair growth.

And When it comes to specific foods that promote hair growth, the healthy hair all-stars are here. Let’s scroll and check out.


Berries like strawberries, blueberries, and cranberries are readily available in the summer months and can be included in your diet.

Berries contain a good amount of vitamin C and antioxidants, an essential protein required to strengthen hair and prevent breakage.

Sweet potatoes

If you are dealing with hair fall and split ends, then sweet potatoes are a must for you. Sweet potatoes contain beta-carotene, which the body converts into vitamin A, which is further linked to good hair health.

Vitamin A promotes sebum production, strengthening hair roots, promoting hair growth, and preventing them from breaking.


Intake of biotin is essential for your body to make keratin, a hair protein responsible for making hair stronger, smoother, and shinier.

Eggs are a fantastic source of protein and biotin, which are highly beneficial for your hair. But if you don’t eat eggs, you can try avocado. They are also a rich source of biotin.


The wealth of folic acid and antioxidants present in papaya enhance the circulation of blood, oxygen, and nutrients to the hair follicles and promote the growth of healthy hair.

According to a 2012 study, the vitamin A in papaya helps your scalp produce sebum, nourishing and strengthening your hair. So without delay, include papaya in your daily diet.

Bell peppers

Red, yellow, and green bell peppers are delicious vitamin sources necessary for hair growth.

The vitamin C present in bell peppers helps in the production of collagen in the body that keeps the hair healthy and helps in optimum levels of hair growth.
