Se nota un cabello mas grueso. La presentacion es pequeña, pero no necesitas mucho para limpiar bien el cabello. No hace que te salga mas cabello, pero ayuda a fortalecer el que tienes y darle mas cuerpo.

UPDATE: After 35 days of use I see obvious improvement. The short, fine hairs at my hairline (particularly at the temples) NEVER seemed to grow UNTIL I started using Nioxin 35 days ago. Hair at my temples was very sparse and my scalp showed through. Now it’s nearly filled in. I can’t honestly say if there is more growth on top of my head yet, but the hair seems much fuller. I realize it takes time for growth that begins below the surface to become apparent. In the meantime, I’m thrilled that my hair has become soft and so much more manageable. Another plus, just a small amount of shampoo and conditioner quickly turn into a rich lather. I don’t think I’ll ever use another product again. Purchased the 30 day supply. I’ve used the product generously and still have a lot left after 35 daily shampoos. Highly recommend it. Posted 35 days ago: I’ve been worried about thinning hair for a long time (female, 77). Decided to try this before Rogaine. Instructions say you must use it every day for the first month. I don’t usually wash my hair every day because it’s shoulder length, but I’m willing to put forth the extra effort to gain fuller hair! It has been 10 days since I began the regimen and my hair feels transformed! The shampoo and conditioner lather up super fast and have a really nice, light fragrance. The final step takes me a few extra minutes because I want to be sure to get good scalp coverage (be sure to shake the bottle until you don’t hear the contents moving), then I use a wide tooth comb to distribute it through my hair. I know it’s too soon to expect to see new hair growth on my scalp, but my center part and extreme thinning at the temples seem very much improved due to the new appearance of fullness. My hair feels like it’s alive again - nice movement and soft feel. I can’t wait to show my hairdresser! I should also note that I also began to massage my scalp twice daily to stimulate root growth. I’m all in on this product. Have taken multiple brands of hair growth pills, and have taken Biotin (5,000 mg) for many, many years. Working only from the “inside” hasn’t done it for me, but I am VERY hopeful that adding this product and working from the “outside” will be a game changer. I will update in a few months, but I have high hopes due to the new silky texture and fuller appearance.
