What are the Reasons for Slow Hair Growth?

There are tons of different factors that can cause slow hair growth. We may not realize it at first, but it is quite easy to avoid most of these troubles if we know what they are.

In this article, we’ll take a look at five factors that slow hair growth. While there are hundreds of different factors, these five are some of the more common ones. You will likely have at least one, if not more of these active in your life.

If you would like to know some of the more common reasons for slow hair growth and hopefully deal with them, if possible, then read on!

Unbalanced Hair Cycles

Your hair goes through cycles. This three-part cycle always happens in the same order.

However, sometimes the length of time between each section gets muddled up. Here are the basic meanings of each section:

·         Anagen (Growing Hair Phase)

·         Catagen (Renewing Hair Phase)

·         Telogen (Hair Loss Phase)

Your hair follicles start out in the Anagen phase, move into the catagen phase, then end in the Telogen phase. After the Telogen phase has completed, the hair follicle will again begin at the Anagen phase and start growing a new hair strand.

Your hair follicles are rarely in sync with one another. Some of them will be in the Anagen phase while others may be in the Telogen phase. This is good because if they were in sync, we would all go bald every once in a while!

The problem with this is that some people have a genetic disability. Your hair cycle is dependent on your genes as much as it is your health. Some families tend to have a genetic lean toward the Telogen cycle, meaning their hair follicles remain in this phase longer than most other people.

When this happens, you’ll find yourself with bald spots every now and then, until eventually, those hair follicles start dying and the bald spot never goes away!

Unfortunately, this is one of the factors that can’t be corrected fully. However, if you do have this problem, you can try to hide it by growing out the hair that is in the Anagen and Catagen phases and combing it over the missing hair.

Sudden Temperature Changes

Whether your scalp suddenly gets hotter or colder, the effect is essentially the same. It messes up your hair follicles and slows your blood flow rate down. The result of this change is that your hair follicles will slow down the hair production process.

Should you expose your scalp to sudden temperature changes too often, you may find yourself balding at an early age. Eventually, the hair follicles will give in, one by one, and die off. When a hair follicle dies, that particular hair strand is gone for good!

Too Much Sugar in Your Diet

Too much sugar has interesting effects on your bloodstream. In this case, it secretes a particular hormone that causes your hair follicles to shrink. Eventually, the hair follicle shrinks to the point where it falls out of your hair follicle altogether.

While eating too much sugar won’t kill your hair follicles and cause permanent baldness, it can and will give you temporary bald spots. These bald spots will remain there until you balance the sugar levels in your system. (Essentially by cutting out many of the sugary foods that you must be eating)

Stressing Out

If you stress yourself out on a daily basis, your brain will tell your hair follicles to stop working. The stress also tends to make your hair fall out completely. (Or some of the hair strands, at least)

If you have bald spots or slow hair growth because of stress, it is only temporary. As soon as you remove the stressful factor from your life that is causing you to feel this way, your hair follicles will begin working again. Eventually, your bald spots will get covered in hair again.


Water is essential to your entire existence. Without an adequate supply of water, all of your bodily processes will slow down.

There’s a reason why we can survive without food for 35-40 days, but we can only survive 3 days without water. While the idea that we all need 8 glasses of water each day is inaccurate, you should still be sure to drink water every few hours to keep yourself hydrated. A dehydrated body creates a huge number of problems.

Your hair growth will slow right down if you don’t have enough water. The dehydrated brain will determine that hair growth is far less important than many other body functions. Because of this, your hair will grow incredibly slowly until you start hydrating regularly.

These are five of the many reasons for slow hair growth. If you notice any of these matching your current situation, try to work around them and see if your hair starts to grow faster. Good luck!
