It has not been very long since hair filler has been introduced. A lot of people might not even know about what hair filler is. So, let’s start with a brief introduction about what hair filler is. It is basically an injection which is injected into your scalp in order to produce more hair. Isn’t that amazing? No surgery, no medicine, just an injection which goes into your scalp and start its reaction very quickly. There are a number of hair fillers out in the market but let’s talk about the one I have tried for myself which is “Dr CYJ hair filler”. I later buy this filler from Hyaldirect and my experience was awesome.
