    Worth the price!

    This is a bit of a long review but well worth it. I promise you. I am a 69-year-old woman who has very sparse eyebrows so had them micro bladed about seven years ago. Most recently I wanted to have the Microblading removed because now it looks more like a light tattoo. However, in the consultation with the technician, she said some people are surprised after removing the Microblading because they have very little hair and now it’s even more noticeable without the color from the Microblading. I told her I would think about it but on the way out I noticed they were selling this product. They told me that it really works. So I actually decided not to have any tattoo removal and thought I would try the Obagi serum. At just four weeks I cannot tell you the amount of hair growth I’m experiencing. I am truly shocked. The packaging says it takes about three months, but I’m at four weeks and I am so very pleased. I can’t imagine what two more months is going to look like! It is well worth the price and I will continue to use it. Don’t be afraid to invest in it, you will not be disappointed.

    The best

    I have tried many eyebrow serums, but this one is the best. I am finally seeing some hairs in that area, where I haven’t seen for years. It is such a great product.
