Yes, our hair is affected by various factors in our lives, such as:
Hormonal Imbalances
Excess androgens (male sex hormones) contribute to male pattern baldness. This is related to an increase in an androgen called dihydrotestosterone (DHT). DHT binds to hair follicles and stops hair growth, and it may also decrease the life span of a hair follicle overall.
Thyroid Problems
Both hypothyroidism (an underactive thyroid) and hyperthyroidism (an overactive thyroid) cause hormonal imbalance, which results in hair loss or hair thinning.
Thyroid-related autoimmune diseases, such as Graves’ disease and Hashimoto’s thyroiditis, can also limit new hair from growing.
Scalp Infection
Many scalp conditions and infections can cause hair loss. These include:
- Folliculitis
- Ringworm
- Piedra
- Seborrheic dermatitis
- Scalp psoriasis
Certain Medications
A number of medications can cause drug-induced hair loss as a side effect or allergic reaction.
Some medications that can potentially make men lose hair include blood-thinning medications, beta and calcium channel blockers, anti-inflammatories, and drugs for depression.
Trichotillomania
This condition is also known as hair-pulling disorder and is thought to be closely related to obsessive-compulsive disorder and other types of anxiety disorders.
It is characterised by urges to compulsively pull out hair from the scalp area, eyebrows, eyelashes and other areas of the body, which is often accompanied by a sense of relief or pleasure.
Nutrient Deficiencies
Deficiencies in certain vitamins and minerals can lead to hair loss and reduced hair growth. These compounds usually aid in the growth cycle and cellular turnover.
Insufficient protein, vitamin D, biotin, collagen, zinc and iron are deficiencies that can cause hair loss.
Physical Trauma and Stress
When your body is under severe physical stress, the natural growth phase cycle of hair growth can be disrupted, leading to hair loss.
A shock to the system — such as a severe accident, surgery, or serious illness — can also shock the hair follicles and cause hair loss that may occur even months after the stressful event.
