Zhang Guang 101B Hair Shedding Proof Tonic 120ml – Rare in UK Original Zhang Guang 101B Hair Tonic. Very difficult to find in the UK.

This product is known for helping with hair shedding and supporting healthier hair growth. I personally found it to be a really good and effective treatment. ✔️ Original product ✔️ Approx. half bottle left ✔️ 120ml bottle ✔️ Rare & expensive in UK
