You are going about your daily hair care routine when you notice that your hair is losing its volume and thickness. Though thinning hair is a common symptom of hair loss, you don’t have to fret about it. It can be triggered by certain medical conditions, hormonal changes, lifestyle factors, and even nutrition deficiencies. This post exposes the many reasons your hair may be thinning down and provides some treatment options to thicken it. Keep reading.

Causes Of Hair Thinning

Genetics, lifestyle, and hairstyling habits are three of the most common factors that cause hair thinning. If you have a family history of hair loss and alopecia areata, you have greater chances of experiencing it.

The following hairstyling and lifestyle habits may contribute to hair thinning:

  • Excess use of styling products like gels and hairsprays can damage your hair and cause thinning.
  • Frequent chemical and hair treatments like coloring, perming, and relaxing may damage the hair.
  • Tight hairstyles may also cause hair loss. The tightness and pressure on the hair roots may cause breakage and hair thinning over time.
  • Lack of nutrients like iron and folic acid may also cause hair fall (1).
  • Stress is linked to hair loss (2). Physiological stress like surgery, pregnancy, trauma, and psychological stress caused by any personal crisis may trigger hair loss.
  • Hormonal imbalances, especially after childbirth, may trigger hair loss (3).
  • Sudden weight loss causes physical stress to your body and may lead to hair loss (4).

Medical conditions, such as autoimmune diseases like alopecia areata, and immunodeficiency conditions may also trigger hair loss (5). If you notice unusual hair loss, consult a doctor immediately and follow the prescribed treatment method. Here is what you can also do to minimize hair loss.

Treatments For Hair Thinning

1. Scalp Massage

Scalp massage encourages blood flow, softens the scalp skin, and feels extremely relaxing. A study found scalp massages to stabilize hair loss and promote regrowth in people with hair loss issues  (6). However, further studies are required to evaluate the efficacy of scalp massages for hair growth.

2. Aromatherapy

Aromatherapy is not directly linked to hair growth and loss. However, aromatherapy and essential oils can calm your mind, help you relax, and reduce stress (7). This, in turn, minimizes hair fall.

3. Anti-Thinning Shampoos

You will get prescription and OTC shampoos for hair loss at drugstores. Prescription shampoos contain anti-androgenetic ingredients that may prevent hair loss caused by DHT (a type of androgen). On the other hand, OTC anti-thinning shampoos contain amino acids and antioxidants that nourish the follicles to reduce thinning and inflammation. Consult a doctor for product recommendations.

4. Take Multivitamins

Malnourishment caused by eating disorders can cause nutritional deficiencies and trigger hair loss and thinning (8). Often, fad diets cause a nutritional imbalance in the body. Deficiency of nutrients like iron, folic acid, amino acids, vitamins B12 and D, and zinc may trigger hair loss (1). Consult a nutritionist or dietitian for a specialized diet chart. Also, talk to the doctor and get blood tests done to determine any nutritional deficiency.

5. Folic Acid Supplements

Folic acid is a type of vitamin B that helps in new cell generation. It helps the hair follicles to grow new hair (1). To combat folic acid deficiency, consume foods rich in the nutrient, like Brussel sprouts, spinach, and broccoli. You can also take folic acid supplements.

6. Apply Minoxidil

Minoxidil is a topical medication for hair loss treatment (9). This over-the-counter medication promotes new hair growth and covers bald patches. However, consult a doctor before using minoxidil as unregulated usage of the medication may cause allergic reactions.

7. At-Home Laser Therapy

Low-level laser therapy stimulates weak hair follicles and promotes hair growth (10). Usually, laser therapy is done under a doctor’s supervision.

However, you will also get at-home laser devices to combat hair loss. These devices target the hair follicles with the laser of a specific wavelength to promote hair growth. Compared to medical-grade lasers used by the doctor, at-home devices are less effective and take longer to show results.

Apart from these treatments, you can take the following steps to prevent hair thinning.

Tips To Prevent Thinning Hair

1. Consume A Protein-Rich Diet

Your hair is made of protein (keratin), and that is why following a protein-rich diet can encourage thicker hair growth (1). Consume foods like fish, poultry products, dairy, and meat. If you are vegetarian, you may take protein supplements to meet the requirement.

2. Avoid Tight Hairstyles

Hairstyles like tight ponytails, buns, or tight braids expose the hair roots to constant pressure. This may cause hair loss or traction alopecia. Using heat styling devices and excess styling products can further worsen the damage. You can reverse this by trying more relaxed hairstyles like loose braids and buns.

3. Take Vitamin Supplements

Vitamins D and B12 are crucial for hair growth, and their deficiency may cause hair thinning and loss (11). It may also hinder your natural hair growth. Consult a doctor to determine the deficiency and take supplements to meet the daily requirements.

4. Scalp Maintenance

A healthy scalp is crucial for healthy hair. Follow good hair care practices to maintain scalp health. Oil regularly to keep your scalp and hair moisturized. Avoid excessive use of heat styling devices and chemical treatments like bleaching and coloring. Use mild shampoos and conditioners and a clarifying shampoo once in a while to remove product buildup.

5. Never Forget Conditioner

The hair from the middle to the ends is away from the scalp and devoid of natural oils. To keep it healthy and prevent dryness and breakage, use a hydrating conditioner that contains ingredients like panthenol and glycerine.

These hair care and healthy lifestyle practices will help you maintain scalp and hair health and minimize hair fall. However, if the hair fall is uncontrollable, consult a doctor immediately.

When To See A Doctor

Despite following proper hair care practices and maintaining a balanced lifestyle and diet, if you notice excessive hair fall, consult a doctor right away. Your hair fall may be caused by an underlying health condition and may require medical intervention.

Thinning hair is one of the common symptoms of hair loss. Your hair may lose volume and thickness due to nutritional deficiencies, hormonal changes, medical conditions, and lifestyle factors. Tight hairstyles, excess use of styling products, and frequent chemical treatments may also contribute to hair thinning. You can go for scalp massages, aromatherapies, anti-thinning multivitamins, supplements, and laser therapy to treat this condition. Understanding the cause of your hair loss is important to determine the treatment method. You may have to follow a balanced lifestyle, proper diet, and right hair care routine to maintain hair health.
