    Why is it that companies discontinue products that they can’t keep in stock? Is there something else like this? I have used BioSilk products for over 25 years and I even kept it at the college where I taught for the dogs. I just bought some more for my Long Coated German Shepherds. I just wish it had a better fragrance.
    Thank you

    I went to my local Sally Beauty store to get more Silk21 serum and to my dismay and disappointment I learned that this product has been discontinued. Like the reviews above, my question to you is WHY?? This is hands down the best serum I have ever used, and I have been using serums for a long time. Bring it back!!!!!

    This is the BEST serum I have ever used on my hair. It made my over-processed 46 year old hair feel and look healthy and younger. I am very unhappy that Salley’s discontinued this product.
