Summary

Researchers are testing a synbiotic formula called BLHK03 to see if it can reduce hair loss caused by chemotherapy in women with breast cancer. The trial includes 7 women with stage I to III breast cancer who are scheduled for chemotherapy with anthracycline or taxane drugs. Participants receive either the synbiotic or a placebo, and researchers measure hair loss using the Dean scale and track changes in gut bacteria.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A synbiotic formula called BLHK03, which combines probiotics and prebiotic compounds
What this could lead to
If it works, this could offer a way to reduce hair loss from chemotherapy, helping women keep more of their hair during breast cancer treatment.
What could go wrong
This is a very small pilot trial with only 7 participants, so results may not be reliable or apply to everyone. The supplement might not reduce hair loss, and its effects on gut bacteria are still uncertain.
