Review on Full Shine Extensions Double Seamless by Rachel Johnson

My hairdresser used this brand and advised me to buy two 50g packs of 1b color for my hair. My length is above my collarbone and I wanted it to be under my bra strap so I ordered 22 inches. Upon opening the package, she immediately noticed how "thin" they were compared to other Full Shine tapes she had worked with. I really wanted them to be ready before Christmas, so we put them in anyway, thinking we could just cut them off or mix them in if they weren't thick enough. Well, they're not fat enough. General. It looks stringy and so far from my natural hair. She advised me to buy another pack or two because they were about 1/2 thicker than the other 50g she was using. Her clients are mostly blondes so I'm not sure if darker shades are thinner or maybe I just have a bad batch. I've tried looking at the boxes and they don't say 50g anywhere so maybe they sent me 30g? Very disappointed because I paid over $100 and I don't get it back. But I'm too insecure to fret. Now I'm spending another $51+tax on 22"50g extensions and hope they're thick enough. :(
