1. Didn't darken my hair.

   My findings & comments on this product: Nova9 Ganoderma Nutrient Hair Darkening Serum.
   1. I ordered this product because it states it is a serum for "Natural Anti-Greying, Thicker, Longer Hair-Growth". As I recently found a couple of grey hairs in my fringe I decided to give it a try.
   2. The first thing I noticed about the product was the instructions given on the box. It states that you should "comb your hair with an air cushion to loosen pores, then scrape your head with a scraping board until it is hot". What?
   3. Anyway I applied the product to my hair after brushing it, and then massaged it in to my scalp. Then left it on overnight. and washed my hair the next day, and repeated the application again that night.
   4. After the second application I washed my hair the next day and was horrified to find a large part of my fringe was full of grey hair. In fact it was so noticeable that I swore up a storm.
   5. It seems I must have had a bad, or rather reverse reaction to using this product, and I won't be using it again.
   6. At time of ordering the product cost £5.56. Value for money? No.

2. Nutrient Hair Serum

   I can't give this product more than four stars. I've been using it for a few weeks and haven't noticed any significant change in my hair colour so far. I'll continue using it because it has worked well as a conditioner. My hair looks healthier, feels softer, and is noticeably less frizzy.

   My biggest issue was understanding the unusual instructions, which I found confusing and unnecessarily complicated. They refer to tools such as an air cushion comb and a scraping board, neither of which I had to hand. In the end, I found a much simpler application method worked perfectly well.

   I applied the product directly to my scalp while wearing rubber gloves and left it on for about an hour before shampooing it out. The oil is very lightweight, absorbs quickly, and doesn't leave my hair feeling greasy or weighed down.

   I also didn't experience any irritation, redness, or discomfort on my scalp, which is important as I'm always cautious when trying new hair products.

   Overall, I haven't seen the hair colour results I was hoping for, but it has performed well as a conditioning treatment and has improved the overall appearance and manageability of my hair.

3. Smells nice but no effect in darkening or thickening hair

   I have tried out a few different lotions and potions for conditioning, thickening and growing hair so I thought I would give this a go for a while.
   First the good. I really like the smell, kind of organic and nutty. It feels nice in the hand and on the hair.
   But fur me I have noticed no improvement in hair thickening and in darkening my very greying/whitening hair.
   At the time of review this was a little under £6, which is cheap, but if it doesn't do very much then it's money wasted.
   Maybe it will work differently for others but for me this isn't effective in either of the claimed effects.

   Nova9 Ganoderma Nutrient Hair Darkening Serum exceeded my expectations with its noticeable results and gentle formula. My hair looks naturally darker, healthier, and more vibrant after consistent use. I appreciate that it nourishes the scalp while improving hair texture and shine. The serum feels lightweight, non-greasy, and easy to apply daily. Overall, it’s a great product for anyone looking to enhance hair color while maintaining hair health.

5. Confusing instructions, decent feel but results unclear

   PeterVerified review from Amazon.co.uk

   I’m a bit on the fence with this serum. The first thing that put me off was the instructions, which are honestly very strange and poorly explained. References to things like special combs and scraping boards aren’t clear at all, and I had to ignore most of it and just apply a few drops directly to the scalp. Once you get past that, the serum itself is very lightweight, almost watery, and absorbs quickly without leaving any greasiness, which I do like. The smell is a little odd at first but thankfully fades quite quickly. After a few weeks of use I haven’t noticed any real change in hair colour or thickness yet, so it feels very much like a “wait and see” product. It’s not unpleasant to use, but between the confusing instructions and lack of visible results so far, I can’t rate it higher than three stars.

6. Conditions well.

   GCVerified review from Amazon.co.uk

   Reviewed in the United Kingdom on 1 January 2026

   This isn't a dye, from my understanding it is intended to nourish hair and naturally reduce greying and restore faded colour. That means any changes will be gradual and I can't say I've seen any visible results in my first ten days of use. However, it does make a good conditioner and my hair feels silkier. There's a slight scent, the closest comparison I can make is similar to natural vanilla, which fades after a while and is not unpleasant. In fact the scent and consistency of this reminds me of a beard condition I used to use. I'm happy with this as a conditioner, will update this review if I detect any colour change.

7. Will give it time, not oily, smells pleasant.

   Been using this for around week now, can not say i have noticed any difference to my grey hair, looks the same colour to me.
   On the plus side it make my hair soft and not oily and only a slight smell.
   Instructions are off putting, scrape your head with a scrapping board until its hot, i will not be scrapping my head with a board until its hot, very weird, i think its lost in translation.
   I will give it more time and see if my grey goes darker and will update this review.

   I’ve been using this Ganoderma Nutrient Hair Darkening Serum daily — it feels nourishing and calming on the scalp, and I love that it’s unisex and gentle. The serum claims to support healthy hair growth from the root, moisturise dry ends, and help maintain natural colour while preventing premature greying.My hair looks fuller and smoother, with a softer feel and improved manageability. It’s an easy addition to my hair-care routine and a good choice for anyone wanting thicker, healthier-looking hair with less fuss. Highly recommend!
