1. Warm temperatures and sunshine
Normally, hair grows about 1 to 1.5 cm per month, but in the summer, hair grows faster in the sun. This is due to the higher temperatures and increased light exposure .
Because you spend more time outdoors in the summer and the sun shines longer, your hair is exposed to more light. This stimulates cell growth throughout your body, including your scalp.
In the warmer seasons, hair cells divide and form faster than in winter. At the same time, direct sunlight provides your body with increased levels of valuable vitamin D.

During the winter months, however, many people suffer from a vitamin D deficiency, which negatively impacts hair growth. Unlike all other vitamins, vitamin D can be produced by the human body itself.
The prerequisite for this, however, is that your body receives sufficient sunlight . If this is the case, the cholesterol that builds up in the skin is converted into the important vitamin D.
2. Lots of fruit and vegetables
The fact that more fresh fruit and vegetables are eaten during the warmer seasons also has an extremely positive effect on hair growth.
Especially on very hot days, many people prefer a light salad to a heavy meal. This also benefits your hair growth, as a balanced and healthy diet is important for providing the hair roots with sufficient nutrients .

A fresh and healthy diet ensures a balanced vitamin balance during the warmer months. This is due, among other things, to the fact that many fruits and vegetables contain the valuable hair vitamin biotin , which is largely responsible for strengthening cells and is therefore important for skin, hair, and nails.
In summer, people generally eat less and eat fresher foods. Furthermore, most people drink more in the summer, which is also very important for hair growth.
3. Relaxation and wellness
Summer is the main vacation season for many people. Therefore, it's also the perfect time to speed up hair growth. Stressful periods and tension can negatively impact hair growth.
In summer, many people's moods are already lifted by the increased heat. Those on vacation in the summer can truly relax, which has a positive effect on hair growth in the sun. Stress is a common cause of hair loss .
Especially on vacation, you should treat yourself to a complete wellness program. A gentle scalp massage with various oils, for example, is a pleasant experience. Massaging the scalp promotes blood circulation and thus stimulates hair growth.
4. Let hair air dry
In winter, your hair is often exposed to the dry air from heating and blow-dried after showering or bathing. This much heat is very damaging to your hair. It removes moisture, causing it to dry out and become brittle or fragile.
Air drying, on the other hand, is a real pleasure for the hair, leaves the scalp and hair sufficiently moisturized and is used more often in summer.

In summer, neither a hot shower nor a long, hot bath is necessary. Your hair will also appreciate this. During warmer temperatures, most people tend to just take a short, cool or lukewarm shower . This is good for hair growth.
It's recommended to alternate between running cold and lukewarm water over your head. This further stimulates blood circulation in the scalp and thus promotes hair growth.
5. Salty sea air
Those who vacation by the sea during the summer benefit even more from the warm season. The alkaline salt content of the water and the fresh air ensure less dandruff forms on the scalp . Especially if you're already prone to dandruff, a vacation by the sea can work wonders.
The salty air also absorbs excess oil, making hair less greasy . The alkaline salt content ensures that thick hair becomes smoother and less greasy.
A sea salt scrub can also promote hair growth by gently removing dandruff and dead skin particles from the scalp. A vacation by the sea is also always a treat for the soul.
Conclusion: Summertime is the optimal time to grow your hair
Hair needs light for vitamin D to grow, so hair grows faster in the sun than during the darker season. A fresher and healthier diet with plenty of fruit and vegetables during the warmer seasons also has a positive effect on healthy hair growth .
In addition, summer often offers a little more time to recover and truly relax your body . A vacation by the sea has a particularly positive effect, as the alkaline salt content prevents dandruff from forming on your scalp.
By the way, summer is also the ideal time to undergo a hair transplant. This way, you can combine the surgery with a wonderful vacation in Turkey and fully recover after the hair transplant.
