Name Ingredients:
Vitamin K2, or menaquinone, is one of the three types of Vitamin K. It has a range of functions within the body, including calcium metabolism, which may be beneficial to hair health.
Key insights:
- The in vitro evidence suggests that Vitamin K2 can inhibit calcification. Scalp calcification (in which excess calcium builds up in the scalp tissue) can damage hair follicles and induce hair loss due to less blood flow. However, there have been no in vivo or clinical studies to support the use of Vitamin K2 in hair loss.
- Our experience tracking members: Vitamin K2 is not enough to improve hair growth outcomes.
