What Causes Damaged Hair For Men?

There are many culprits that conspire and make up dry hair, eventually leading to damaged hair for men.

1- Too Much Sun Exposure

For men, exposure to ultraviolet (UV) light from both natural and artificial sources can be damaging to your skin, and yes, it can damage your scalp, including your hair’s outer layer (hair cuticle).

When this is damaged, it isn’t able to hold and lock moisture effectively, resulting in dry or brittle hair.

EXPERT NOTE: For safety, health experts say that you need to go out either early or late in the day [1]. Refrain also from staying longer than ten (10) minutes under the heat of the sun.

2- Excessive Shampooing

Washing your hair with shampoo is an obvious way to clean your oily hair. However, doing this too much will actually give you unhealthy hair instead of a healthy one.

Shampoo cleans the hair and also rids it off of all the nutrients and relevant oils in the scalp, resulting in dry hair.

3- Too Much Chlorinated Water Exposure

Repeated exposure of your hair to chlorine not only reduces the natural oils in the hair but can also cause tons of chemical reactions in it. 

Excessive exposure of your hair to chlorinated water tends to weaken each hair strand, and at the same time, make each hair follicle vulnerable.

4- Heat Damage

Hair damage from heat can happen anywhere along the hair shaft, and quite possibly, your scalp.

Heat hair damage comes not only from sun exposure but also from hair products and equipment like a hairdryer, flat iron, chemical treatments, and other hair professional heated tools.

5- Thyroid Problems

Last, but most definitely not least among the most common causes of hair damage for men is the complication of the thyroid.

Apparently, both hyperthyroidism and hypothyroidism [2] are known to cause hair loss. As a matter of fact, this type of hair loss involves the entire scalp, not only certain areas.

How Can Guys Tell if Their Hair is Damaged? 

The lack of moisture, hair loss, as well as high porosity hair is among the many signs of hair damage.

There are no particular hair types that are more prone to dryness and damage. It can affect curly hair, straight hair, or whatever shape or form of hair there is.

1- Lack Of Moisture

The logic is simple; if your hair appears to be a bit off and dehydrated, then that simply means that there’s something wrong with it.

Watch out if your hair is lacking moisture or if your hair is soaking up more moisture than it should be. This is one of the earliest signs that you have damaged hair.

2- Traction Alopecia (Excessive Hair Loss)

Following the lack of moisture, traction alopecia, a type of hair loss, is also one of the most notable signs that you’re having hair breakage.

The usual cause of traction alopecia is the hard and constant pulling of the hair shaft, which can be because of tight braids and hair ties, ponytails, and buns. 

Another common culprit of hair loss is the lack of protein supplied to the hair.

3- Incorrect Hair Products

Contrary to popular belief, there are certain hair products that are harshly chemically induced, possibly causing extreme dryness to the scalp, resulting in dry hair. 

As much as possible, avoid overusing hair products that contain the following ingredients:

  • Formaldehyde.
  • Alcohol (Isopropyl and Propyl).
  • Silicones.
  • Parabens.

EXPERT TIP: It’s fine to use them lightly and subtly, but the moment you overuse them on your hair, it won’t just promote hair loss, but it can also cause irritation and allergic reactions.

4- High Porosity Hair

A crown of hair that is highly porous means that it’s faster and able to absorb oils, liquids, and other products by your hair, which is good, right?

Unfortunately, it is the other way around. Most products today contain harsh chemicals that, when absorbed by the scalp, can dry the entire area out, giving you a rougher scalp and hair texture.

How to Properly Treat and Care For Damaged Hair For Guys

There are the best ways for men to properly maintain and care for damaged and unhealthy hair.

Among these, the most important ones are to use mild and safe shampoo and conditioner, use olive oil, add moisture to their hair, use almond oil, air dry, and avoid washing it excessively.

Using these products will cleanse and refresh your hair without experiencing the negative effects of using harsh and toxic chemicals.

2- Use Hair Products With Olive Oil

One of the things that you can do to make sure that your hair is kept healthy is to use products that contain olive oil.

This ingredient helps in rehydrating and in smoothening the hair cuticle, replenishing it, and feeding it with all the moisture needed.

3- Add Moisture to Your Hair

The right balance of moisture is key in making sure that your hair is kept hydrated. If you’re unsure of this, you can add in extra moisture from a few selected hair products.

You can consider using a different shampoo and conditioner with argan oil, almond oil, castor oil, and jojoba oil. You can use a leave-in conditioner, cooler water when you wash your hair, etc.  

These natural ingredients not only help add moisture to your hair but also make it shinier and healthier. 

EXPERT TIP: You can use direct oil extracts of jojoba oil and almond oil, as well as natural ingredients of the same kind, and apply it directly to your hair.

These are the things that helped a multitude of men that had damaged hair.
