I couldn't think of an alternate yet equal word for godsend... but that what this shampoo has been for me! It is the ONLY product that has worked to stop my hair loss and REGROW it. I have Lupus so I cycle in & out of periods where I shed more hair than most, but last year the "shedding" was evolving into severe thinning and balding in the area directly above my temples. Thin & balding hair is not a great situation for anyone, but being a "young" woman in my late 30's with healthy, long & thick hair who was suffering with thinning hair to the point of creating bald spots & a receding hairline was a very depressing situation which started to make me very self conscious... but not anymore thanks to this shampoo! Shortly after I starting using it I noticed a big reduction in the amount of hair that would collect at my shower drain. That in itself was wonderful to see, but now after using this product for almost a year the regrowth I have at my hairline and balding spots is around 3" long and thick! I am SO grateful for this product and for my friend who recommended it to me. I just bought an extra bottle for my dad, and I hope he experiences the same amazing results as I have. Thank you!!
