Today, many promising treatment options are available to men experiencing hair loss. There are safe and effective ways to restore your hair, whether your hairline is receding, your crown is losing thickness, or you have thinning hair all over your scalp. Early treatment of male pattern baldness achieves a more optimal outcome.
The overall goal of treatment in AGA is to arrest miniaturisation and improve hair density.
Finasteride 1mg daily is FDA approved for the treatment of male pattern hair loss, and it is the most effective way to prevent hair loss in men. The influence of finasteride on hair count is most significant on the vertex scalp. It can improve hair density on the frontal scalp to a lesser degree and is least effective in the temporal regions. Finasteride can also enhance hair calibre. Patients who fail to respond in the first year are likely to be non-responders’ long term. Finasteride needs to be continued indefinitely to maintain efficaciousness. Side effects of finasteride include lowered libido, erectile dysfunction, reduced ejaculatory volume, temporary reduction in sperm count, testicular pain, depression and gynecomastia.
Topical finasteride may be a good alternative for men who are uncomfortable with oral finasteride. The topical administration of finasteride can reduce systemic effects associated with its mechanism of action by inhibiting 2-α reductase in the scalp. Compared to oral finasteride, it has a markedly lower systemic exposure and less effect on serum DHT levels.
Topical finasteride has only been studied as a topical treatment for androgenetic alopecia in a small number of randomized controlled trials. These studies, however, show promising results and non-inferiority to systemic delivery.
In the current market, topical minoxidil and finasteride are combined in a variety of formulations.
Topical minoxidil is available over-the-counter and in various strengths, up to 5% solution. Higher strengths are more effective. Minoxidil has been shown to prevent hair loss in 2 out of 3 men. It prolongs the anagen phase of the hair follicle and transforms the miniaturised follicles into terminal hair follicles. Several meta-analysis studies have confirmed the high quality of evidence for using minoxidil to treat male pattern hair loss. The most common adverse effects are pruritus and local irritation with resulting flaking. The latter is usually due to propylene glycol or alcohol in the formulation of the drug.
Dutasteride is now considered a treatment option in male pattern baldness due to its good response shown by various studies and meta-analyses. In most of these studies, dutasteride was found to be better than finasteride with similar adverse effects. In the UK, dutasteride is not yet approved for the treatment of hair loss, and its use is off-label. Dutasteride, however, might become a treatment of choice for AGA in the future.
Low-level laser therapy and Micro-needling may also help prevent hair loss in men, especially in combination with pharmacologic therapies. Additional studies are required to define and validate optimal treatment protocols.
Androgenetic alopecia progresses over time, and although the currently available medical treatments like finasteride and minoxidil are effective in arresting the progression of the disease, they allow only partial regrowth of hair. While progress has been made in the medical management of androgenic alopecia and several physical therapies are emerging, hair transplantation remains the best treatment for advanced disease.
