Spectral.BRD is a serum that offers an integrated approach to improve the even coverage of your beard. To stimulate a thicker and fuller beard, the most effective, clinically proven ingredients have been combined to create a serum that promotes fuller density, stimulates growth and improves facial hair quality. To increase the number and quality of terminal hairs per square cm in your beard or mustache, Spectral.BRD uses powerful hair growth stimulating ingredients such as Nanoxidil, Piroctone Olamine, Adenosine and other active ingredients. Nanoxidil is a patented molecule with high efficacy, low molecular weight and no known side effects. Piroctone Olamine causes an increase in the number of hairs in the anagen (growth) phase in 33% of people by more than 10%. 88% of people taking Piroctone Olamine report noticeably thicker hair. Adenosine has also been shown to increase the anagen phase of hair growth and increase the diameter of the hair shaft, while adding to the overall thickness of your beard. Content: 30ml
