Sweating And Hair Growth: The Truth

Sweat glands are located throughout our bodies. They secrete sweat to cool us down during exercise or hot weather. 

This natural body function helps regulate body temperature and internal health. It is essential for overall health; it also aids hair growth.

Sweating helps eliminate waste and toxins by excreting sweat from the sweat glands. Nonetheless, excessive sweating and your hair care routine can affect your hair and scalp and lead to hair loss.

Does Sweating Affect Hair Growth?

Sweating is a natural body reaction that helps regulate body temperature.

Sweat levels vary for each individual. Due to physical exertion, lifestyle, daily activities, medical conditions, exercise routine, and hormones, Some may experience excessive sweating or mild sweating.

Nonetheless, perspiration is an essential body function for every individual. It helps release feel-good chemicals that can improve your mood and help unclog clogged pores and fight against germs.

Nearly 1 liter of sweat released from your body each day has several advantages, ranging from detoxification to good hair development.

Sweating from your scalp unclogs your hair follicles to allow new hair growth. It also opens up the pores on your scalp, releasing any build-up that may be preventing your hair from growing.

Although sweating opens up your hair follicles and promotes new hair development, the salty sweat build-up on your scalp is terrible for your hair.

This is because salty perspiration contains lactic acid, which can badly affect your hair when combined with keratin.

Although it is advisable to work out regularly so that your scalp sweats, it is also critical to wash your hair afterward, so that surplus sweat doesn’t stay on your head for an extended period.

Is Sweat Bad For Your Hair?

Sweat is not completely bad for your hair. Like overall wellness and skin health, it also improves hair growth.

It will accumulate on your scalp while you exercise or engage in other physical activities (and the rest of your body).

Fortunately, sweat isn’t intrinsically detrimental to your hair; it’s what you do with it before, during, and after that determines the effects on your hair made and how healthy your hair is.

This is where it might affect your hair if you let the sweat in your hair dry after your workout or activity.

Once sweat dries out on your scalp, it can combine with bacteria and irritate or harm your scalp. It can also affect your hair follicles.  

If your hair has been dyed, the excessive salt concentration can affect the color.

Your hair is prone to breakage when it is wet, so how you style your hair while doing activities that make you sweat is also important. 

Does Excessive Sweating Cause Hair Loss?

Heavy sweating is typical at times. When you exercise, when you are too hot or scared, you may sweat profusely.

Teenagers typically sweat more than they did when they were younger. Sweat glands in teenagers develop in tandem with the rest of their bodies.

Menopause also causes women to sweat profusely on occasion.

 Factors that can contribute to excess sweating and hair loss include;


Your stress levels and anxiety can increase your sweat levels, causing you to sweat more.


Sweating is a natural reaction to heat. The sun, as well as high temperature, can harm both your skin and hair. However, you can manage this by maintaining a regular hair care routine even in humid conditions. 

Spicy Food

The food you eat can also make you sweat. This is due to an active ingredient known as capsaicin, often present in spicy food.

It stimulates your nerves and gives you a mild warming sensation, making you sweat more when eating spicy food.

Other factors that may trigger excess sweat include overactive sweat glands, physical exertion, and hormonal changes. While excess sweating might not cause hair loss, your hair care routine can damage your hair afterward.

Does Too Much Exercise Cause Hair Loss

Although everyone’s definition of excessive exercise is different, it can be described as an activity that negatively influences your everyday life and causes injuries or tiredness.

The quantity of exercise that can be considered excessive is relative. It all relies on your circumstances and how you feel about the amount and intensity of your performing activity.

Excessive exercise can cause components of perspiration such as natural and water to clog and damage your hair follicles, resulting in hair loss. It can also lead to telogen effluvium, also known as increased hair thinning.

Hair products containing essential oils and staying hydrated are two ways to help combat this.

How To Stop Sweat From Damaging Your Hair

There are a few options for absorbing perspiration, especially if you sweat a lot in your hair.

  • Wear a cotton headband across your hairline to absorb some of the sweat.
  • Dry shampoo is an excellent alternative for removing extra moisture from the scalp.
  • Use protective styles like flat twists to stay cool and sweat less through your workout. It’s good to draw your hair back and away from your face if your hair is long enough to bun.
  • Do a conditioner rinse after working out.

 Fill a spray bottle with a conditioner and dilute with water. Spray this mixture to mist your hair and rinse it out with water. You may also use a leave-in conditioner of your choice.

  • Avoid excess spicy foods and caffeinated drinks as they increase heart rate, raise blood sugar levels, and activate sweat glands.
  • Finally, you should consume water before, during, and after your workout. Staying hydrated will help you stay cool while preventing your body from overheating.

Although sweating is vital to your hair growth, skin condition, and overall health, it is crucial to practice good hygiene, exercise regularly, stay hydrated, eat healthily and avoid foods that aggravate sweating.

Stop all activities that may aggravate your sweat levels. If you experience excessive sweating with no particular cause, you should see a doctor.
