Your hair is one of the most important characteristics of your physical appearance. It can be frustrating if you find it stops growing or isn’t growing at the pace or length it should. But did you know that there are several internal and external reasons why your hair may not be growing?
Hair may not grow because of internal reasons such as stress, poor diet, pregnancy, childbirth, certain drugs, hormonal imbalances, surgery, genetics, and age. External causes include product ingredients, tight hairstyles, product build-up, environmental factors, and over-processed and dry hair.
While slowed or lack of hair growth exists and can be challenging, there are solutions. Read along to learn more about why your hair growth cycle might be disrupted and what you can do about it.
Internal Causes for Lack of Hair Growth
Hair grows at a pace of half an inch every month on average. As a result, the typical person’s hair increases by about 6 inches each year.
This is affected when internal factors in the body and lifestyle hinder your hair growth cycle.
Check out the reasons discussed below:
The connection between hair loss and stress is something we hear about regularly. Stress majorly affects a person’s health in every way.
And that is the reason why you often read or hear professionals and experts talk about how reducing stress is so essential.
Hair can be affected by stress in any form, whether physical or mental. It makes your hair more prone to gray prematurely and reduces the strength of the hair follicle, which may lead to your hair not growing (or hair loss).
Telogen effluvium is a form of hair loss in which hair falls out quickly in short periods. It typically occurs after your body has been subjected to something physically or emotionally stressful (i.e., physical trauma, illness, fever, sudden weight loss) and can also result from sudden hormonal changes.
While it’s difficult to avoid stress altogether, you can take measures to manage and reduce it. Practices like yoga, professional therapy, journaling, exercise, and essential oils can help to calm the mind and body.
Like with other elements of health and beauty, your diet has a significant impact on not just the condition but also how quickly your hair grows. Nutritional deficiency is one of the most common reasons for hair not growing.
Vitamin and mineral supplementation may aid with hair loss. Vitamins and minerals are essential for healthy cell development and function, and a lack of these nutrients may lead to your hair not growing.
While supplements are readily accessible and affordable, it’s crucial to understand which vitamins and minerals are required to treat hair loss.
Check with your doctor or a nutritionist to see if you’re deficient in nutrients, and ask for advice on which supplements to take.
Hormonal changes that occur during menopause may also cause telogen effluvium. As estrogen levels decline, more hair enters the resting phase. This can lead to increased hair loss and slowed hair growth.
During pregnancy, more hair is in the growth phase for longer periods, and hair loss is reduced. But around three to six months after childbirth, some women experience massive hair loss. This is called Postpartum Telogen Effluvium, caused by the sudden hormone change.
The good news is that this form of hair loss is usually temporary and resolves itself within six to twelve months.
During this period, you can bump up your hair care routine and diet to provide your hair with extra love and attention so it does not become a more severe or long-term issue.
Certain medications and recreational drugs can cause hair loss. If you suffer from a health condition and take chronic or specific medications to target particular issues, your hair growth cycle can be affected.
Some of the most common drugs that are associated with hair loss include:
- Accutane, a medication used to treat acne
- Chemotherapy drugs
- Blood pressure medications such as beta blockers and ACE inhibitors
- Some birth control pills
- Hormonal imbalance
- Hormones can fluctuate for various reasons, including thyroid disorders, stress, menstruation, and puberty.
An imbalance in hormones can lead to hair loss and stunted hair growth. If your hair growth is stunted, it is best to consult a doctor and check your hormone levels to get to the root of the problem.
There are a variety of reasons why your hormones may be affected. Once you get it checked, you can identify and address the root of the problem.
Surgery can lead to hair loss depending on the procedure type, length of hospital stay, drugs used, and general nutritional status. It’s not unusual for people to have significant hair loss after surgery, and it may take months to grow back.
Hair loss can be caused by contact with poisonous chemicals in metal. People who work with metals, such as in a factory or workshop, may be susceptible to metal toxicity and hair loss.
Hair loss can also be hereditary. If your parents or grandparents have a history of hair loss, you may also be more likely to experience it.
The hair growth cycle is unique to each individual, and proper hair care with a healthy lifestyle can reduce the chances of the pattern being carried over.
The hair growth cycle changes as you age, and hair becomes thinner. This is a natural process, and very little can be done to stop it.
You can only take steps to try and maintain healthy hair. It is important to use gentle, nourishing hair products and avoid over-styling.
A lifetime of using heat styling, chemical processes such as bleach and color, and a less-than-ideal diet may weaken your hair as you age.
Additionally, the scalp produces less oil as we age, resulting in coarser, drier hair and a higher risk of breakage.
If you experience excessive daily hair shedding for more than three months or significant shedding that has not improved despite treatment, see a trichologist or your doctor, as there could be an underlying factor that needs to be addressed.
External Factors for Hair Not Growing
If you’re having trouble growing hair, reviewing all aspects of your lifestyle is crucial to see if anything can be improved.
External factors can also significantly affect your hair growth cycle and lead to substantial hair loss.
The following are some of the most common external reasons for stunted hair growth:
Heat Styling Tools
It can change your hair’s natural texture, weaken strands, and cause long-term damage like hair loss.
Reduce your blow dryer from high heat to a medium or low (cool) setting. Alternating or going an extra day without heat can improve the condition of your hair.
Hair Care Product Ingredients
Some ingredients can benefit hair health and help promote growth, while others can cause more damage.
Tight ponytails and buns might look nice, but they can cause serious damage to your hair health. Trust me. I have experienced this firsthand. Elastic bands pull the hair strands causing friction which may lead to fraying and split ends.
Braids are another style to avoid overdoing to preserve your hair’s health. Extremely tight braids can physically pull the hair away from the roots, causing splitting, hair, and follicle damage, leading to breakage, hair fall, slowed growth, and weak strands.
Your scalp may be suffocating due to oil and grime. Product, mineral, and dirt build-up can hinder your hair’s ability to grow properly. The grime can clog the follicles and prevent treatment products from being absorbed properly.
Many folks rush or skip the conditioning process during hair care. But it is vital to feed your hair with the necessary nutrients and moisture.
When washing your hair, leave your conditioner in for a few minutes, concentrating on the mid-shaft and tips. And don’t rush this process!
If your hair isn’t getting the attention or care it requires and is breaking off at the same rate as it grows, it will stay the same length all year unless you change your level up your hair care routine and change things around to give your hair what it needs to thrive.
The most common type of hair breakage is caused by improper handling and excessive use of heat-styling tools, chemicals, and dyes.
Using too many chemicals or dyes may make your hair dry and lifeless. Bleach and other products that strip your natural oils or are infused deep into your hair shaft and scalp can hinder your hair growth and cause damage.
Try to keep color and chemical treatments at a minimum and give your hair plenty of time to recover between sessions.
Trauma to the Scalp
If you have an injury on your scalp and got surgery or stitches, that section of your scalp might struggle with regrowth.
Chemical treatments can also cause burns and damage to the scalp and disrupt the hair growth cycle.
Pollution, smoke, sun exposure, and other toxins can also affect hair not growing. This might be difficult to avoid, but you can take steps to reduce being affected.
Lack of Exercise
Both exercise and a healthy diet are essential for hair development. Exercise regularly to increase blood flow and promote hair growth.
Blood flow to your scalp is food for your roots and follicles. A lack of it will drastically reduce hair growth and cause hair fall.
Too many Split Ends
Split ends may not stunt your hair growth, but they limit the progress of your hair growth. This is because they take away from the length of your hair. They also cause breakage.
You want to ensure your hair gets proper nourishment from root to tip to prevent split ends.
When you notice split ends, ensure you get a haircut as soon as possible to prevent split ends from traveling up the hair strands and causing more damage.
Every six to eight weeks is a suitable time to get a haircut when struggling with split ends.
How To Improve and Promote Healthy Hair Growth
You can do several things to help promote healthy hair growth, both from the inside and outside. Below are some tips:
From the inside:
Follow a healthy diet with plenty of iron-rich foods and protein. Try to avoid excessive calorie restriction and try your best to reduce stress.
From the outside:
Use good quality products designed for your hair type, and avoid using heated styling tools as much as possible. Try to limit your exposure to environmental factors that can damage the hair shaft.
If you continue to experience problems with your hair growth cycle, it’s best to consult your doctor or a trichologist to get correctly diagnosed and treated.
Now you have more insight into why your hair may not be growing or why you experience significant hair loss.
Professional help is always advised to ensure you’ve covered all your bases. You can start your journey to long and healthy hair with the proper diagnosis.
