Hair loss, or alopecia, is a condition that affects both men and women and can have a significant impact on psychological well-being. The etiology of hair loss is multifactorial, encompassing genetic predispositions, hormonal influences, medical conditions, medications, and environmental factors. Understanding the underlying causes is essential for effective management and treatment..
This blog delineates the principal causes of alopecia and diagnostic methodologies, and explores therapeutic interventions for the treatment of androgenic alopecia, the most common type, including the integration of Platelet-Rich Plasma (PRP), Platelet-Rich Fibrin (PRF) and Microneedling,
Alopecia Types
Androgenetic Alopecia (AGA): AGA is the most common form of hair loss, characterized by a patterned distribution. It is influenced by androgens and genetic predisposition. In men, it presents as receding hairline and vertex balding, while in women, it manifests as diffuse thinning over the crown.
Alopecia Areata (AA): AA is an autoimmune condition resulting in patchy hair loss. The exact pathogenesis is unknown, but it involves an immune-mediated attack on the hair follicles.
Telogen Effluvium: This is a form of non-scarring hair loss characterized by diffuse shedding of hairs entering the telogen phase. It is often triggered by stress, illness, hormonal changes, or medications.
Tinea Capitis: A fungal infection of the scalp, primarily affecting children. It can cause patchy hair loss with associated scale and inflammation.
Scarring Alopecias: These conditions, including lichen planopilaris and frontal fibrosing alopecia, result in permanent hair loss due to destruction of the hair follicle and replacement with scar tissue.
Diagnostic Approaches
Clinical Evaluation: A thorough history and physical examination are crucial. The pattern of hair loss, presence of scaling or inflammation, and signs of systemic diseases can guide the diagnosis.
Scalp Biopsy: A biopsy may be necessary for diagnosing scarring alopecias or when the clinical picture is unclear.
Laboratory Tests: Depending on the clinical context, tests may include thyroid function tests, serum iron levels, complete blood count, and hormonal assays to rule out underlying conditions.
Androgenic Alopecia (AGA) Treatment Modalities
Medical Treatments:
o Minoxidil, originally used to treat hypertension is now the gold standard for the of alopecia : Topical minoxidil solutions or foams are commonly used. Minoxidil promotes hair growth by enhancing blood flow to hair follicles, prolonging the anagen (growth) phase, and shortening the telogen (resting) phase.. They are effective in both men and women. Minimal side effects, such as scalp irritation, are possible.
o Finasteride and Dutasteride , tipically taken in pill form, are 5-alpha-reductase inhibitors used primarily in male AGA to reduce hair loss and promote regrowth. Finasteride blocks (5-alpha-reductase), the enzyme responsible for converting testosterone into dihydrotestosterone (DHT). DHT plays a crucial role in the progression of pattern hair loss. By reducing DHT levels in the scalp, finasteride reverses the process of hair loss. However, it typically takes at least three months of daily use before noticeable improvements occur. Continuing the medication is essential to maintain results; discontinuing it may lead to reversal of effects within 12 months13. Some users may experience sexual side effects (e.g., decreased libido). Pregnancy is an absolute contraindication as it can affect the fetus genitalia developmental. Patients should not donate blood while taking finasteride to prevent transmitting it to pregnant females through blood transfusion.
o Topical Minoxidil and oral 5-alpha-reductase inhibitors (Finasteride, Dutasteride) remain staples for AGA . More recently, oral minoxidil and topical finasteride has been used to reduce the incidence of side effects with similar efficacy.
Surgical Treatments
o Hair Transplantation: Surgical relocation of hair follicles from a donor site to balding areas is a primary treatment for AGA.
o Scalp Reduction: Removal of bald scalp with closure or stretching of hair-bearing scalp can be considered in selected cases.
Emerging Therapies
o Platelet-Rich Plasma (PRP) and Platelet-Rich Fibrin (PRF): These autologous therapies, derived from the patient's own blood, harness growth factors to rejuvenate and stimulate hair follicles. PRP, through its rich milieu of platelet-derived growth factors, promotes angiogenesis (blood vessels growth) and follicular proliferation. PRF, a second-generation platelet concentrate, offers a sustained release of growth factors, enhancing the regenerative process.
o Microneedling: This technique induces controlled dermal injury via fine needles, stimulating endogenous repair mechanisms and enhancing cutaneous absorption of topical therapeutics. When synergized with PRP or PRF, microneedling amplifies the follicular response, fostering an environment conducive to hair growth.
o Exosome Therapy: Exosomes, extracellular vesicles laden with bioactive molecules, have emerged as a frontier in regenerative medicine. Their application in alopecia targets the modulation of hair follicle microenvironments, promoting cellular communication and angiogenesis, thus facilitating hair regeneration.
o Trans Epidermal Delivery Systems, like ALma TED, use ultrasonic enegy waves to create microchanels in the scalp and deliver propietary solutions containing growth facrors, peotides, vitamns and nutrients without the need for injections to stimulate hair growth. The treatment also stimulates collahgen production imrpoveing the scalp health and creating an environment that promotes hair growth .
Lifestile and Nutritional Support
Adequate nutrition, stress management, and avoiding hair-damaging practices can support overall hair health.
