Is Sweat Bad for Your Scalp and Hair?

via The Beauty Brains

Sillabear says… I am looking for ways to minimize the amount of times that I wash my hair and I recently came across information that utilizing a mixture of 1:2 parts of peppermint oil to jojoba oil will break down the salts that are deposited on the scalp from pores after a strenuous exercise. Is this true? If not, do products such as dry shampoo rid one’s scalp of these potentially damaging salts?

The Beauty Brains respond:
Before we talk about sweat removal let’s do a quick recap of what’s in sweat.

Sweaty chemistry
Our bodies sweat through two different glands: eccrine (which are found pretty much all over the body) and apocrine (which are concentrated where there are hair follicles.) Both glands produce sweat that consists of water and minerals (or salts). Specifically, sweat contains sodium, potassium, calcium, and magnesium. But only the apocrine glands product lactate, urea, and other substances which make this milky sweat so tasty to odor causing bacteria.

Peppermint oil or jojoba oil have no special ability to breakdown or remove sweat. Peppermint oil could have some antibacterial properties which might inhibit some of the odor associated with eccrine gland perspiration but it is also a mild irritant and may end up making your scalp inflamed. The “stuff” you’re trying to get rid of like salts, Sodium lactate and urea are water soluble so jojoba oil won’t do much to remove them either. A dry shampoo which contains a water absorbent starch might help “soak up” some of these materials if you’re that determined to get them off your scalp. Which brings us to the main point of this post…


Is sweat bad for scalp?
Why do you think that salts from sweat are damaging in the first place? And what exactly do you think is becoming damaged? Your skin? Your hair? That may not be the case! In fact, some of the components of sweat have skin moisturizing properties. (Lactate and urea are found in many skin lotions.) And there’s some evidence that suggests sweat may actually keep you healthy by helping to ward off certain microorganisms.

The Beauty Brains bottom line
If you’re sweaty and stinky you should certainly clean up as needed. But if you’re just worried about sweat “damaging” your scalp or hair it’s probably less of a problem than you realize.
