A 2013 study and 2017 study found the use of microneedling to be promising in stimulating healthy hair growth - especially when combined with other modes of treatment, such as minoxidil - one of the most commonly used medications for the treatment of hair loss.
It brings us back to our first question: Can microneedling improve beard growth? And if it does, how will it give you a thicker, fuller beard?
The thing is, the effectiveness of microneedling in treating alopecia (hair loss) is backed by some research, but quantifiable data is still required to understand its efficiency in improving hair growth in other parts of the body, such as the face. So, until significant research is carried out to test the growth-inducing effect of microneedling on the beard, we’ll never know for certain.
That said, because microneedling stimulates collagen and elastin production, it should give you a fuller, thicker beard, too.
How does that work out?
Well, collagen consists of a collection of amino acids, an organic compound referred to as the building block of life. Our hair follicles use this compound, among many others, to produce keratin, which is associated with hair growth and strength.
Hence, microneedling may help improve beard growth. It does that by healing damaged skin, improving nutrient-rich blood flow to the area, and activating stem-cell factors. Because the procedure is done with needles, there will likely be some bleeding, irritation, redness, and inflammation, but these effects will disappear once your skin starts to heal.
