Less shedding…

I have long course hair. I was noticing more shedding recently. Not sure why but alas, I thought I would give this a go and try it. I have noticed less shedding. I use the hair serum along with the a red light therapy brush from a different brand. I’m going to stick with it and hopefully continue to see improvement.

Great Scalp Serum Without the Grease

Lightweight, non-sticky, and easy to add to a daily routine. A great option if you’re focused on scalp health and strengthening thinning hair.

Obagi Scalp Serum Works!!!

I started with the brow and lash serum and moved on to scalp serum. Why didn't I start with this??? When Obagi comes to the hair growth table, you should follow! I've been taking hair growth supplements and trying various hair growth products for years so I can say with experience, Obagi and all their highly paid scientists developed a formula that works!

Scalp serums are all the rage!

As we age, so does our hair (along with everything else!). I have been spending more time (and money) on taking care of my scalp. My friend (who specializes in all things beauty) recommended this product and I have been impressed so far. The applicator makes it easy to apply the product right on the roots and while it may make your hair a little damp upon application, but the next morning, hair is dry and not greasy. I have only been using it for a few weeks but my hair seems thicker and has more volume. I am definitely going to keep using this product.

Minor improvement

I was hoping to see much more new hair growth after two weeks, but it has been minimal. The formula is not greasy or sticky, so it does absorb well into the scalp. I will stick with it for a little while to see if the product generates more hair growth.

Promising Results

I’ve been using this product once a day for a full month and I like what I’m seeing. It gives me volume without stickiness and I also see thinning areas with new baby hairs growing. I have tried other products for hair thinning before, but I felt compelled to write a review about this one, because the others can take months to work. My only complaint is the price, but I find it lasts longer than other products I’ve tried with a lower price. I also wanted to share that I apply the serum on my finger tips, rub the finger tips of both hands together, then apply on my scalp, focusing on my thinning areas.

Great serum!

This serum is so easy to apply. It leaves no residue behind. No smell at all. I use it each night. It has been only a few weeks and I’m seeing some baby hairs at the temple area which is my primary area of concern. Obagi is a trusted brand for results!

Some New Growth

I have been using this product for about 3 weeks now and I have noticed some sprigs of new growth about 3/4 of an inch on the top of my head and around the hairline and temple area. I really need some new growth on the sides as well, but not seeing it yet. I have very high hopes that very soon I will see new growth in this area. When I do, I will enter a new review. So for now, i am very happy with the product and will keep using it. Thank you Obagi for this product!

Obagi Nu-Cil

I haven't used it long enough to know if it will do what it says it will, however, it does leave the hair a bit sticky so best used just after washing rather than on dry hair. Hoping it does some good....

Haven’t used long enough to notice

I have not been using long enough to see a difference. Although, I do like that I can apply morning and/or night and it doesn’t not affect the condition of my hair or scalp. It’s totally scent free and very light weight. I’ll update after I use the tube to see if I had any new growth.
