A recent clinical trial has explored the use of a new drug called topical cetirizine in the treatment of patients suffering from hair loss or alopecia.
Hair loss is a common problem that can affect both men and women, and it can have a significant impact on a person's quality of life, confidence, and self-esteem. Androgenetic alopecia, also known as male or female pattern baldness, is the most common type of hair loss, affecting millions of people worldwide. Hair is lost in a well-defined pattern, beginning above both temples. Over time, the hairline recedes to form a characteristic "M" shape.
Androgenetic alopecia is a genetic condition that occurs due to the excessive effect of hormones called androgens which are produced in the body to regulate sexual development.
There are many treatments available for this type of hair loss such as topical minoxidil, platelet-rich plasma (PRP), various oral drugs and supplements, and hair transplant surgery. All of these treatments have their side effects and doctors have been continuously looking for newer drugs with lower negative effects.
One of these drugs is topical cetirizine which can be applied directly to the skin. It is an antihistamine that is commonly used to treat allergies, but it has also been found to have anti-inflammatory properties that may be useful for treating hair loss. Although this drug has been in use for many years, strong clinical evidence justifying its use in preventing hair loss has been lacking.
