Efficacy over ingredient abundance.
The number of ingredients is often seen as a sign of sophistication. Some competitors include 25, 26 or even 45 (often without scientific grounding).5
LH23 takes a scientific approach. Rather than starting from a list of classic hair-care ingredients, the formula was built by identifying the biological processes behind hair fall and hair growth, then working back to the source to select botanical actives with targeted functional properties.
