Why Is My Hair Falling Out So Much
Hair loss, clinically referred to as alopecia, represents a prevalent dermatological condition that affects individuals across various demographics and ethnicities. It is characterized by the abnormal shedding or thinning of hair, which can significantly impact the psychological well-being and social interactions of affected individuals. While it is normal for adults to shed between 50 to 100 hairs daily as part of the natural hair cycle, concerns arise when the rate of shedding surpasses the rate of regrowth.
As we proceed, you will discover not only why your hair might be falling out but also all possible solutions to address this condition.
What Are the Symptoms of Losing Hair
The symptoms of hair loss can vary widely depending on the underlying cause but typically begin with noticeable changes in hair thickness and volume.
Common signs include a receding hairline, thinning patches especially on the top of the head, and more hair than usual collecting on pillows, in shower drains, or in hairbrushes.
Some individuals may also see broadening of their part or bald spots suddenly appearing.
Understanding the Complete Hair Growth Cycle
The hair growth cycle is a sophisticated biological process divided into four distinct phases: anagen, catagen, telogen, and exogen. Disruptions to this cycle are directly linked to various forms of hair loss.
Anagen Phase (Growth Phase)
This is the longest phase of the cycle, lasting between two to eight years. During this phase, cells in the root are dividing rapidly, adding to the shaft. Approximately 85% to 90% of all hairs are in this phase at any given time.
Catagen Phase (Transition Phase)
Following the anagen phase, the cycle enters the catagen phase. This short phase, lasting about two to three weeks, serves as a transitional period during which the follicle contracts and detaches from the dermal papilla (a structure that feeds the follicle). Growth stops, and the follicle undergoes structural changes.
Telogen Phase (Resting Phase)
Lasting approximately two to four months, the telogen phase is a resting period. While growth does not occur during this phase, it doesn't fall out either. The old hair remains in place as new hair begins to form in the follicle.
Exogen Phase (Shedding Phase)
This is the final phase of the growth cycle. The exogen phase is an extension of the telogen phase where the old hair is shed, and new hair continues to grow. Typically, shedding 50 to 100 hairs a day is considered normal as these hairs are in the exogen phase.
What Are All the Possible Causes of Hair Loss
Hair loss is influenced by a complex interplay of genetic, hormonal, environmental, and health-related factors. Understanding the myriad causes and identifying the risk groups can help in managing and potentially mitigating this condition.
Genetic predisposition
Genetic predisposition is a primary factor in many types of hair loss, where sensitivity to dihydrotestosterone (DHT) leads to follicular miniaturization.
Hormonal Influences
Hormonal changes also play a role, particularly in conditions like postpartum hair loss and menopause-related shedding.
Medical Conditions
- Thyroid disorders: Both hypothyroidism and hyperthyroidism can cause thinning.
- Polycystic ovary syndrome (PCOS): This condition often includes symptoms such as thinning and hirsutism due to hormonal imbalances.
- Autoimmune diseases: Conditions like lupus and alopecia areata involve the immune system attacking follicles.
- Infections: Fungal infections like tinea capitis (scalp ringworm) and bacterial infections can lead to patchy loss.
- Iron and protein deficiencies: Essential for health, deficiencies in these nutrients can result in shedding.
- Eating disorders: Anorexia and bulimia can lead to severe nutritional deficiencies, impacting growth.
- Chemotherapy and radiation therapy: These cancer treatments are notorious for causing anagen effluvium, a rapid and extensive loss.
Psychological and Physical Stress
- Telogen effluvium: Severe stress can push hair follicles into a resting state, resulting in diffuse hair shedding.
- Trichotillomania: This hair-pulling disorder is often triggered by stress and can cause uneven bald patches.
Dermatological Conditions
- Seborrheic dermatitis: This inflammatory skin condition can cause scaly patches and dandruff that may lead to hair thinning if not properly managed.
- Psoriasis: Though primarily a skin disease, when it affects the scalp, it can lead to temporary hair thinning.
