Re-grew My Eyebrows!

My brows nearly disappeared. At least two inches from outer ends had only a few hairs hanging on for dear life. The inner portion of both brows were going fast and fading in color. I was considering tattooing before they disappeared altogether. Obagi Nu-Cil save me. brows are full again from inner to outer portion and they're darker than I remember. This sounds like a fabrication, but it isn't. It's great to have one problem solved!

Obagi Nu-Cil Eyebrow Boosting Serum

I purchased this product hoping for results and boy did I get them! My eyebrows grew in thicker and darker. I had to get them threaded and thinned out. Most definitely recommend this product.

The only thing that works!

I've tried many brands. This is the only one that works. I do have to use it every single day, if I skip a day, I notice hair loss (might not happen to others, but I had long covid which oddly caused continued brow hair loss issues). It's a pricey product but worth every penny and I use as the last step of my makeup application to tame my brows also! I usually buy two or three at a time whenever I can catch sales here because it's a product I never ever want to run out of.

Worked awhile

Worked great at first, then didn’t notice much growth after continuing. Undecided if I will continue use of any brand for eye brown growth.

It really works!

This serum really works! I was considering getting powder brows because my eyebrows had become so sparse. After using this serum, my brows filled in enough that I no longer needed the procedure. I don’t use it daily anymore—only when I notice a few hairs have fallen out. After a short time, they fill back in. It’s now part of my maintenance routine, and I love the results.

Good product

I’ve just begun to use the product so I have not given it enough time to see the full results but it goes well and makes my brows feel good and look better.

Thumbs up for this product

I have used Obagi products for 20 yrs. Love them. Hadn’t seen this eyebrow boosting serum. A friend recommended it. It took about one month for me to notice new growth so stick with it. It also makes your eyebrow color much darker. Great product.

Miraculous Product

This is the real deal, I've spent money on microblading and other treatments but this product is the only thing that I had real results, I finally have my thick and darker eyebrows back in a few weeks I noticed a huge difference, I'm using my second bottle and I'm extremely satisfied with the results.

Amazing

I had chemotherapy 6 years ago and lost most of my eyebrows. I used this product for about 3 weeks and noticed my brows returning. They are now a dark brown and long enough to have them groomed. They are a little sparse on the ends but I fill that in with brow pencil. I am hopeful that with continued use, they will completely fill in. I will definitely purchase again.

It works

The product was recommended by the nurse practitioner at the aesthetics spa I visit. She has been using the product for over a year. When she started she had very thin eyebrows and now has lush brows. At 71, my brows were thinning, so why not give it a try. After only two weeks my brows were noticeably thicker and darker. I do not have to use brow color only gel. Eight weeks into use, people have noticed. I wish all other products performed promises as well as Obagi Nu-Cil Eyebrow Boosting Serum.

I was skeptical, but I thought I would try it because it had so many good reviews. I am happy to say that it really works and I noticed the benefits the first time I used it.

Delivers as promised.

My eyebrows became very sparse this spring. I did not know why, old age. Looked terrible. Taking my vitamins, eating healthy. I use other Obagi products which I love. Noted the reviews on this item, was a bit skeptical, but thought why not- since the other Obagi I use is 5 star. So glad that I did, I have been applying nightly as directed and have noted my eyebrows are no longer losing hair and are filling in again. Very happy about this. Thank you Obagi. Also use the auto refill program to keep me with product and a lower price. Lovelyskin does help you to look your best.

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.

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.
