Hair growth can be stubborn, take its time or sometimes feel as though it is travelling at a glacial pace. If you've made a bold choice and chopped your length dramatically or if your mane has always been a slow grower, speeding up the process is paramount for many at points during their life. Knowing what ingredients to look for, their functions and how they promote hair growth can become akin to unpacking a scientific journal for those less experienced with vitamins and mineral uses. To get you started on your hair growth journey, we've compiled a handy guide on what ingredients to look for and the best hair growth products to shop.

When shopping for a hair growth product, there are a handful of ingredients to look for in the make of the various serums, shampoos or capsules you purchase. These include:
