Nioxin Night Density Rescue Serum for Overnight Hair Thickening

I'm only on day 2 of this Serum so I'll update my review once I've given it time for results. But the first impression is great. It smells amazing, feels tingling and amazing, makes my scalp feel clean and refreshed. I was skeptical of it not leaving a greasy feeling in your hair after the nightly treatment but the next morning my hair still felt great! I'm hoping it builds root strength and decreases hair breakage as advertised but my first impression is 5-stars.

I've noticed that my hair has been falling out in clumps in the shower pretty consistently for a while now. My hair used to be pretty thick, but I've noticed recently that my pony tail was looking a lot thinner than it used to, which was a little upsetting. 🫠 I've tried a few different hair loss/hair fall shampoos and serums over the year and I finally found one that works for me! I used this for a week and I feel like I noticed that the hair fall I had in the shower had reduced significantly! At first, I thought that maybe it was a coincidence, but even since I've started using this consistently every night, I haven't had another instance of increased hair fall in the shower. I've been using this every night (2-3 droppers full) all over my scalp. It works well on dry or damp hair, as it has alcohol in it, making it dry pretty dang quickly. It smells really nice, does not leave any sticky residue, and leaves a nice minty feeling on your scalp after you work it in there. I think my only problem with this is that, the instructions says to use 2-4 droppers each time. However, I find that if I keep doing that, I'll go through the bottle way too quickly and this stuff is NOT cheap. I may have to try using a little less each time, and hopefully it still works. Obviously, my personal experience is anecdotal, and depending on what the cause of your hair loss is, this product may not work for everyone. But for me, this stuff is like liquid gold in a bottle! This review isn't sponsored or anything (though, I'd definitely love it if it were 👀), just wanted to share my personal experience.

After changing medications, including addition of Ozempic (GLP-1) into my medication list, within 3 months my hair started to thin more then normal. My hair is long and waist length, normal shed is about 100 hairs a day, but this had increased. I increased protein intake which did help. I have always taken MSM (Methylsulfonylmethane) supplements which have given me very thick hair, and have continued them ( 2000 mg daily) I have been taking Minoxidil generic 5%, for about 5 years already ( to combat post menopause hair thinning) which continued to help. But due to a drug reaction, (not the glp, another rx) I became severely sick, could not eat or drink much for two weeks, ended up the the hospital for a week, had a platelet transfusion. I was very sick. I am ok now, but after leaving the hospital I began losing baseball sized wads of shed hair daily. My hair had dramatically thinned. From a medium ponytail to a pencil sized tail. Probably have lost 3/4 of my hair thickness. Then I started this product, within 3 weeks less hair was dropping, and after about 4 -6 weeks, hair thinning is down to less then 50 strands a day. Dramatic difference when I brush hair. I still need to regrow lost hair, which usually takes about 6 weeks to get going, and it i will be awhile for it ta catch up enough to be noticed in my length and fullness. But less shed is amazing. I apply daily, many drops all over entire scalp (not just three like listing says) - Fully recommend this! Update added. Its been 4-5 months since orginal review. Still using, and recommending this product. I now loose maybe 10 to 12 hairs aday in normal shedding. My hair is super super thick, and length is growing as well. Still taking Ozempic, but you would never know from my hair thickness. At age 61, it's the fullest it has ever been. Much fuller then in my youth. Still using minoxidil, and MSM supplements. Highly recommend this product.

This product does not grow new hair, but it can certainly make your existing hair thicker. I would wake up in the morning with much thicker-looking hair. But then I would shower and lose it. So, I know I put it on after my shower and then dry my hair. It starts thickening up quickly and lasts all day. Try it the morning if you are a morning shower person.

I'm not totally sure what type or specific category of voodoo magic this is, but I've been converted. consistency of water, and dries just as fast, if not quicker than water. does not leave a hint of grease or residue on hair, scalp, or pillow. scent is light but pleasant. bottle is bigger than i expected. directions say to apply 3-4 drops nightly, but i do about 7-10 tbh. it literally dries so quick and i cant feel it, so it sometimes leaves me like "did it even go on?" but it must, because i got actual real life results. within like 3 days my hair looked healthier. within a week i had about half the amount of hair falling out in the shower and during the day. after 2 weeks, one of my widening parts definitely looked fuller. the other widening part i haven't noticed a change though. after 3 weeks, my hair looks thicker and more full, with volume. you must be consistent with this and use it every single night. maybe twice i skipped 2 days in a row and the hair falling in the shower increased like immediately. once i started back up, it decreased again. so idk if that means i just need to use it for the rest of my life...? I'm 1 year post partum, but my hair falling, thinning, and widening parts is like 90% due to age, stress, and scalp flakes/dandruff/seb. dermatitis. 36 year old female.

This didn’t make my hair greasy at all. Easy to apply. I didn’t mind the smell. It’s a menthol fresh scent. I feel like it helped, but I also started multi vitamins at the same time so a combination of both I would assume.

Ive used other things to prevent hair fall. Nothing works like this does. Just stick to it and use it at least 4 times a week. If you are going through menopause I know how you feel. It sucks! But like I said I've tried everything! Use this regularly and your hair will not fall out like it has been. It will return to normal or close to it.

don’t know if works but smells so good

Have religiously used this product since December of 2025, first reaction it made my scalp tingling. Didn’t last long and was able to fall asleep no problem, also the tingling feeling didn’t last longer than a week. Five months in my hair has become thicker I can see hair the hair growth with it as well. Not to mention it feels thicker as well. So glade I had giving this a second chance after having kids. It does take time to work be consistent and patience trust me it’s worth the wait!

Have had exceptionally good results with this product. Use it in conjunction with Rogaine and stimulating roller. I've found that this Rescue Serum is far better than other Nioxin serums for growing hair back and strengthening it too. As to the fragrance, the smell is rosewater. If you don't like that smell you won't like this. I think it's a pleasing fragrance and my significant other likes it too, which is important and she has a very sensitive nose. Upshot is that my hair looks fuller, is healthier and generally easier to style. Of everything I've tried (I'm a guy whose father was bald), this has worked better than everything except Rogaine and using Rogaine alone makes my hair fuzzy and unruly. Am very happy to have tried this serum.

The first time I washed my hair after using this, wayyy less hair came out. And since then, way less hairfall. I have an area on my crown where my hair grows sort of weirdly with less thickness and also fewer hairs in that area, plus I have some other thinning areas. I definitely was not expecting such immediate results though! I really love Nioxin products overall. I also use Nizoral and Zinc every few shampoos, and the rest of the time I'm using System 2 (which I love because it really helps my scalp stay calm).

I’ve only had this a couple of days so I can’t speak to its efficacy, but it is extremely scented, and I love scented products. This is “gets in my mouth” scented. Hopefully it works!!

It works well enough and leaves my fine hair feeling normal, so I don't have to wash it the next day. But for $50, the bottle runs out too quickly because the poor applicator design wastes product.
