Regardless of your gender, this invaluable information is here to help you discover the most up-to-date treatments that can restore your crowning glory and give you the confidence you deserve.
The Cause of Baldness in Men
Balding in men, also known as male pattern baldness or androgenetic alopecia, is primarily caused by genetic and hormonal factors. Key contributors to male pattern baldness include:
- Genetic Predisposition: Specific inherited genes from both parents play a significant role in male pattern baldness. Genes like the androgen receptor gene and variations in the gene for 5-alpha reductase increase the risk of balding.
- Hormonal Influence: Androgens, particularly dihydrotestosterone (DHT), derived from testosterone, bind to scalp hair follicles, leading to their miniaturization over time.
- Age: Male pattern baldness tends to occur with age, typically observed in men over 50, though it can start as early as the teenage years.
- Family History: If close relatives, such as fathers, uncles, or grandfathers, experienced male pattern baldness, the likelihood of developing it is higher due to genetic inheritance.
The Cause of Baldness in Women
Balding in women, known as female pattern hair loss or androgenetic alopecia, has distinct causes:
- Genetic Predisposition: Inherited genes from both parents contribute to female pattern hair loss, involving multiple genes and hormonal interactions.
- Hormonal Factors: Androgens, like testosterone and DHT, affect hair follicles and can lead to their miniaturization. However, hormonal imbalances alone do not fully explain female pattern hair loss.
- Hormonal Changes: Hormonal fluctuations during pregnancy, childbirth, menopause, and conditions like PCOS can trigger hair loss.
- Age: Hair thinning becomes more noticeable as women age, typically occurring after menopause but can start earlier.
- Medical Conditions and Medications: Underlying conditions such as thyroid disorders, autoimmune diseases, and medications like cancer treatments can contribute to hair loss.
- Stress and Lifestyle Factors: Excessive stress, poor nutrition, and unhealthy habits can worsen hair loss in women.
Current Treatments to Treat Hair Loss in Men & Women
There are a number of current treatments for hair loss in men and women that are backed by science. These treatments include:
- Minoxidil (Rogaine): Minoxidil is a topical medication that is applied to the scalp. It works by widening the blood vessels in the scalp, which allows more blood to flow to the hair follicles. This can help to promote hair growth.
Can women use minoxidil? Yes, women can use minoxidil. Minoxidil is a topical medication that is used to treat hair loss. It is available in two strengths: 2% and 5%. The 2% strength is typically recommended for women, while the 5% strength is typically recommended for men. Minoxidil works by widening the blood vessels in the scalp, which allows more blood to flow to the hair follicles. This, in turn, can help to promote hair growth.
- Finasteride (Propecia): Finasteride is a oral medication that is taken once a day. It works by blocking the production of dihydrotestosterone (DHT), a hormone that can cause hair loss. Can women use Finasteride? Due to the potential risks and uncertainties, finasteride is generally not the first-line treatment for female hair loss. Instead, healthcare professionals may explore other treatment options that are more commonly recommended for women, such as topical minoxidil or other targeted therapies.
- Platelet-rich plasma (PRP) therapy: PRP therapy is a procedure that involves extracting platelets from the patient’s blood and then injecting them into the scalp. Platelets contain growth factors that can help to promote hair growth.
- Hair transplantation: Hair transplants are a non-surgical procedure that involves moving hair follicles from one part of the scalp to another. This can be used to restore hair loss in areas where hair has been lost permanently.
Latest Research on Hair Loss Treatments
Exciting developments in hair loss research include the use of JAK inhibitors to promote hair regrowth in alopecia areata, stem cell therapy for hair follicle regeneration, and signaling molecules like SCUBE3 to stimulate hair growth in androgenetic alopecia.
JAK inhibitors are a type of drug that can block the activity of enzymes called Janus kinases. These enzymes play a role in the immune system, and they have also been linked to hair loss. In a recent study, JAK inhibitors were shown to be effective in promoting hair regrowth in people with alopecia areata, a type of autoimmune hair loss.
One of the most recent and largest studies was conducted by the National Institutes of Health (NIH) and published in the journal New England Journal of Medicine in 2022. The study, which was called NCT04597975, involved 1,200 people with alopecia areata who were randomly assigned to receive either the JAK inhibitor baricitinib or a placebo. After 24 weeks of treatment, the people who received baricitinib had significantly more hair regrowth than the people who received the placebo. Specifically, 48% of the people who received baricitinib had at least 50% hair regrowth, compared to 22% of the people who received the placebo.
Another study, which was published in the journal JAMA Dermatology in 2021, found that the JAK inhibitor ruxolitinib was also effective in promoting hair regrowth in people with alopecia areata. The study, which was called NCT04257385, involved 150 people with alopecia areata who were randomly assigned to receive either ruxolitinib or a placebo. After 24 weeks of treatment, the people who received ruxolitinib had significantly more hair regrowth than the people who received the placebo. Specifically, 40% of the people who received ruxolitinib had at least 50% hair regrowth, compared to 15% of the people who received the placebo.
These studies provide strong evidence that JAK inhibitors are effective in promoting hair regrowth in people with alopecia areata. However, it is important to note that these studies were conducted for a relatively short period of time (24 weeks). It is not yet known how long the effects of JAK inhibitors will last, or whether they will be effective in people with more severe alopecia areata.
JAK inhibitors are a promising new treatment option for people with alopecia areata. However, more research is needed to determine the long-term safety and efficacy of these drugs.
Stem cell therapy
Stem cells are undifferentiated cells that have the potential to develop into different types of cells. In recent years, scientists have been experimenting with using stem cells to treat hair loss.
A recent study published in the journal Nature Medicine showed that stem cells can be used to address hair loss. The study, which was conducted by researchers at the University of California, San Francisco, found that stem cells from the hair follicles of mice could be used to regenerate hair follicles in other mice. The study also found that the stem cells could be used to treat hair loss in mice that had been genetically engineered to lose their hair.
The study’s findings suggest that stem cells could be a potential treatment for hair loss in humans. However, more research is needed to determine the safety and efficacy of stem cell therapy for hair loss in humans.
Signaling molecules are chemicals that transmit signals between cells.
In 2022, a study published in the journal Nature Communications showed that a signaling molecule called SCUBE3 potently stimulates hair growth and may offer a therapeutic treatment for androgenetic alopecia, a common form of hair loss in both women and men.
The study was conducted by researchers at the University of California, Irvine, and the Salk Institute for Biological Studies. The researchers found that SCUBE3 is produced by dermal papilla cells, which are specialized cells that lie at the base of hair follicles. SCUBE3 binds to receptors on hair stem cells, which are responsible for producing new hair shafts. When SCUBE3 binds to its receptors, it activates the hair stem cells, causing them to divide and produce new hair shafts.
The researchers also found that SCUBE3 is important for maintaining the normal growth cycle of hair follicles. In mice that were genetically engineered to lack SCUBE3, the hair follicles grew abnormally and the mice lost their hair. When the researchers restored SCUBE3 expression in these mice, the hair follicles returned to normal and the mice grew back their hair.
The researchers believe that SCUBE3 could be a potential therapeutic target for androgenetic alopecia. They are currently developing a drug that could be used to increase SCUBE3 levels in the hair follicles of people with androgenetic alopecia.
These are just a few of the latest scientific studies on hair loss. As research continues, scientists are hopeful that they will be able to develop new and effective treatments for this common condition.
