Infusium 23 is a great produt to use, espiecially if you have frail to thinning hair. it works really well for shine also. ive been back and forth trying other conditioners but theres nothing quite like infusium 23 my hair used to feel so weak and thin but just after a few washes and conditioning with this product your hair will seem alot more fuller it also has a bunch of vitamins that has to be the reason for it working so well after using the product people are always making compliments on how healthy my hair is and looks
