Blown away by results

I thought my thin, over plucked eyebrows were my doom. I started using this serum and was at first startled but then amazed by the growth. I was constant about using it in the beginning and then backed off. Still using it to continue as maintenance. Amazed and delighted! Thank you.

It Works!

This is my second tube of this product. The first was for eyelashes even though I used it on my brows. (The formula is the same.) At first I wasn’t sure but after about 3 months I started noticing my brows filling out. Even though it’s more expensive, I’ll but the product for the brows. The brush is superior to the eyelash brush.

It really works

I've tried other brands (super high end brands) and this one works! I couldn't believe it. Took about a month.

YES!

Finally! A little relief for my sparse eyebrows. Within a few weeks I noticed a difference and even had my brows tinted. People noticed something different but weren't sure what it was. My little secret.

Subtle but definite boost

No unpleasant reaction by my sensitive skin with some obvious quick darkening of existing hairs! Used on both brows for many months now. Over a few weeks one very thin area on one side seemed to fill in a bit. Not expecting miracles. To me it seems the product is helping me retain what I have. Apply to dry skin after shower before makeup. Store tube on its side. Lasts quite awhile.

Amazing!

This serum is easy to apply because of how it’s packaged. Just brush your eyebrows before bedtime. Takes a while but I have seen some results.

I can't believe it works!

I've always been skeptical of brow and lash serums, but this is amazing! My overplucked lashes are thicker, and darker. They've filled in at the ends, as well as along the arch. I boq have a more modern lash line that allows me to have them professionally shaped to enhance my eyes. I will continue to purchase this product.

Still waiting for results

It has only been a a little over 2 weeks since I started using this product on my very sparse brows. The small areas where I have the most hair look a little fuller and a little longer but there is no new growth on the inner corners or arches where there is a single hair here and there. I have residual ink lines from medical tattooing several years ago so at least I have something to follow. I have noticed a little itching but not bad, so far.

Yes, Obagi brow serum is really fabulous because it also makes the hair "darker" as well as fuller!

Acutally works - a nice surprise

I was losing one of my naturally thin eyebrows and looked online for reviews of many products that helped with this type of issue. After reading over a lot of articles, including those written by dermatologists, I decided to try this one as it does not include some ingredients, like others some products do, that can actually change the color of your irises. Well, after only days of use, my eyebrows started to grow in! The only downside is that I do find that the area treated is a bit itchy - but not terribly so - and importantly also - has caused no rash and is therefore tolerable. I am glad I tried this product and will continue to use it.

Seems to be working.

I have used this for a while and although it seems to be working, I don't think I am getting any new brow density. Fortunately, I am maintaining the length and density that began to show up after about two months. I will continue using.
