Name Ingredients:
Lactobacillus rhamnosus is a type of probiotic bacteria naturally found in the intestines. It is commonly used as a supplement for its beneficial effects on gut health, which may also have positive effects on hair health.
Key insights:
- The in vitro evidence suggests that L.rhamnosus can boost gut health by improving the function of the epithelial barrier and inhibiting pathogens. Furthermore, it can increase the production of short-chain fatty acids, which can promote keratinocyte metabolism and exhibit anti-inflammatory effects.
- There do not appear to be any in vivo or clinical studies supporting the use of L.rhamnosus on hair health.
- Our experience tracking members: L.rhamnosus alone is not enough to improve hair loss outcomes.
