I have always had a problem with thinning hair, on and off in the past 10 years or so. I would loose a lot of hair after I washed my hair.
In Feb I tried the Bosley BOS Defence shampoo recommended by my hair stylist. I bought one bottle to try as it was expensive. I researched into the brand, it is an American brand made for thinning hair. I saw great improvement after finishing the first bottle (my family use it as well) And I found it was much cheaper online at Strawberry Net.
Give it a try, its only about $130 for 300ml https://uk.strawberrynet.com/hai ... bos-defense/145490/
