Hair Rejuvenation


Hair rejuvenation refers to the treatments aimed at improving hair health, density, and appearance, often sought by individuals experiencing hair thinning, loss, or quality changes due to various reasons. Medical causes include genetic conditions like androgenetic alopecia, autoimmune disorders like alopecia areata, conditions related to stress or diet (telogen effluvium), side-effects from chemotherapy (anagen effluvium), scalp infections, and hormonal changes. Non-clinical factors include physical and emotional stress, poor diet, aging, harmful haircare practices, and environmental factors. Hair rejuvenation treatments range from topical solutions and oral medications to therapies like PRP and, in severe cases, hair transplants. It’s recommended to consult a dermatologist for personalized advice.


Hair rejuvenation refers to the processes or treatments aimed at restoring or improving the health, density, and overall appearance of hair. It is often sought out by individuals experiencing hair thinning, hair loss, or general changes in hair quality due to various factors. Indications for hair rejuvenation may range from cosmetic desires for thicker, fuller hair to medical necessities due to underlying conditions.

Causal factors for hair degradation requiring rejuvenation can be divided into clinical (medical) and non-clinical (lifestyle/environmental) causes:

Clinical Factors:

  1. Androgenetic Alopecia: This is a genetic condition also known as male-pattern baldness or female-pattern hair loss, characterized by a gradual thinning and loss of hair.
  2. Alopecia Areata: An autoimmune disorder where the body’s immune system attacks hair follicles, leading to hair loss.
  3. Telogen Effluvium: A temporary condition often associated with stress, nutritional deficiencies, or certain medications, where hair follicles are prematurely pushed into the resting phase.
  4. Anagen Effluvium: This condition typically occurs due to chemotherapy or radiation, which disrupts the active growth phase of hair follicles.
  5. Tinea Capitis: A fungal infection of the scalp that can cause hair loss.
  6. Hormonal Changes: Conditions like thyroid disease, polycystic ovary syndrome (PCOS), or changes during pregnancy can influence hair growth and loss.

Non-Clinical Factors:

  1. Stress: High levels of physical or emotional stress can disrupt hair growth cycles, leading to temporary or permanent hair loss.
  2. Diet: Nutritional deficiencies, such as lack of proteins, vitamins (especially vitamin D and B-vitamins), iron, and other essential nutrients, can affect hair health.
  3. Aging: Hair naturally thins and loses its lustre as a part of the aging process.
  4. Haircare Practices: Over-styling, excessive use of heat tools, chemical treatments, and pulling or tugging at the hair (as in tight braids or ponytails) can lead to hair damage and loss.
  5. Environment: Exposure to environmental factors like sunlight, pollution, chlorine in swimming pools, etc., can degrade hair quality.

Hair rejuvenation treatments may include topical solutions, oral medications, light therapy, platelet-rich plasma (PRP) therapy, or in more extreme cases, hair transplant surgeries. The best course of action would depend on the underlying cause of hair loss, the patient’s overall health, and their personal preferences. It’s important to consult with a dermatologist or a hair specialist for personalized advice.



  1. Gradual thinning on top of the head: This is the most common type of hair loss, affecting both men (male-pattern baldness) and women as they age.
  2. Circular or patchy bald spots: Some people may experience smooth, coin-sized bald spots, which can be indicative of conditions like alopecia areata.
  3. Sudden loosening of hair: A physical or emotional shock can cause hair to loosen, resulting in handfuls of hair coming out when combing or washing your hair or even after gentle tugging.
  4. Full-body hair loss: Some medical treatments, such as chemotherapy for cancer, can result in the loss of hair all over your body.
  5. Patches of scaling that spread over the scalp: This is a sign of ringworm (tinea capitis), which may be accompanied by broken hair, redness, swelling, and, at times, oozing.

In terms of diagnosing the causes behind these symptoms, a dermatologist typically uses a combination of the following methods:


  1. Medical history: Understanding any underlying conditions, medications, family history of hair loss, diet, and lifestyle can help identify potential causes.
  2. Physical examination: This includes checking the scalp for signs of inflammation, redness, scaling, and pattern of hair loss.
  3. Pull test: A dermatologist may gently pull on a few strands of hair to determine if there’s excessive shedding.
  4. Blood tests: These can help uncover medical conditions related to hair loss, such as thyroid disease.
  5. Scalp biopsy: In some cases, a small piece of scalp skin may be taken to get a closer look at the hair roots. This can help determine whether an infection is causing hair loss.
  6. Microscopy: Hair strands are examined under a microscope to detect possible disorders of the hair shaft.

Based on the findings, the dermatologist will determine the best course of treatment for hair rejuvenation, tailored to the individual’s specific needs and conditions.

Prognosis and Impact


  1. Androgenetic alopecia: This is a progressive condition, and while treatments such as minoxidil, finasteride, and hair transplants can slow down hair loss and promote growth, they typically do not completely reverse the condition.
  2. Alopecia areata: This condition can be unpredictable, with hair often growing back on its own, although treatments such as corticosteroids can help accelerate the process. However, some people may go on to develop more severe forms of hair loss.
  3. Telogen effluvium: The prognosis for this type of hair loss is generally very good, with hair usually regrowing on its own once the underlying cause (such as stress or nutritional deficiency) is addressed.


Hair rejuvenation can have significant positive impacts on an individual’s quality of life. Hair loss can lead to psychological distress, including decreased self-esteem and confidence, and even depression. By addressing hair loss, rejuvenation treatments can help improve a person’s psychological well-being and overall life satisfaction.

That said, it’s important to have realistic expectations. While these treatments can be very effective, they often take time to work and are not always able to fully restore all lost hair. Side effects can also occur, and these treatments can be costly and may not be covered by insurance. Therefore, the decision to pursue hair rejuvenation treatments should be made in consultation with a dermatologist, taking into account the potential benefits and risks.

Treatment Options

Treatment for hair rejuvenation generally aims to reduce hair loss, promote hair growth, or mask hair loss. The appropriate treatment often depends on the cause of the hair loss. Here are some of the common options:


  1. Minoxidil (Rogaine): This over-the-counter medication is applied to the scalp. It’s suitable for both men and women and helps to promote hair growth and prevent further hair loss.
  2. Finasteride (Propecia): This is a prescription drug for men taken in pill form. It’s not recommended for women of childbearing age.
  3. Corticosteroids: These are prescription medications used for conditions like alopecia areata.


  1. Hair Transplants: This surgical procedure involves moving small plugs of skin, each with a few hairs, from the sides or back of your scalp to the thin or balding areas. The process can be costly and may require several sessions but is often a permanent solution.
  2. Scalp Reduction: This is a surgical process that removes some of the balding scalp, then stretching the hair-filled scalp over the removed area.
  3. Laser Therapy: Low-level lasers are a relatively new method for treating hereditary hair loss in both men and women.

Emerging Treatments:

  1. Platelet-Rich Plasma (PRP): This involves drawing a patient’s blood, processing it so only the enriched cells (platelet-rich plasma) remain, and injecting it into the scalp. PRP contains essential proteins that stimulate natural hair growth.
  2. Microneedling: This procedure uses tiny needles to prick the skin and stimulate new collagen production, and can be combined with other treatments like minoxidil for better results.

Risks and Side Effects


  1. Minoxidil (Rogaine): Potential side effects can include scalp irritation, unwanted hair growth on adjacent areas like the face and hands, and rapid heart rate.
  2. Finasteride (Propecia): Side effects can include decreased sex drive, trouble getting or keeping an erection, and, in rare cases, depression. Pregnant women should not handle crushed or broken finasteride tablets due to the risk of birth defects.
  3. Corticosteroids: Long-term use of corticosteroids can lead to thinning skin, high blood pressure, diabetes, weight gain, osteoporosis, and increased vulnerability to infections.


  1. Hair Transplants: Potential risks include infection, scarring, unnatural-looking tufts of new hair growth, and the possibility that the transplanted hair won’t grow as expected.
  2. Scalp Reduction: Risks include scarring and an unnatural-looking hairline.
  3. Laser Therapy: The main risks with laser therapy are potential skin irritation and the cost, as it usually takes several months and multiple treatments to see results, and insurance doesn’t typically cover it.

Emerging Treatments:

  1. Platelet-Rich Plasma (PRP): Risks include infection, nerve injuries, pain at the injection site, tissue damage, and, rarely, calcification at the injection points.
  2. Microneedling: Potential side effects include swelling, discomfort at the site, redness, and bruising. There is also a risk of infection if the procedure is not performed under sterile conditions.
