The hairdresser recommended this pricey tho not too bad a price + the bottle is good size, I paid $22 but I'd say its certainly well worth every cent. High quality of products, MATRIX BIOLOAGE advanced - full density thickening hair system. My mother had cancer & her hair thinned not too much but she luckly recovered & is healthy & happy but she wanted to find a product of higher quality that would help with thinning hair/weakness, & we love this conditioner. You only need a tiny amount to lather & massage & I leave it in for 2-5mins, it smells lovely, works amazing. It made with Biotin+Zinc PCA+ Gluvo-Omega. Lightweight & results after styling "nourishing and fortifying hair that delivered more body & shine. After drying/straightening my hair was fuller, silky soft, just felt healthy, great on color treated hair, & it locked in a beautiful glossy, shinny finish that allows my newly dyed hair to look bright& vibrant.... I'll purchase again & other products by the company are on my next shopping splurge.
