Product details:
1 x 500ml Herb Spa Anti Aging Shampoo - Vegan | Scalp First | NO SLS / NO SLES
Delay visible signs of scalp aging with every wash. Formulated with SP-3 Complex (30,000 ppm) to help replenish collagen and restore scalp vitality.
SMiB Herb Spa Shampoo is a scalp-first anti-aging shampoo developed to care for the scalp as it naturally changes over time. As we age, collagen levels gradually decline and the scalp loses moisture and essential nutrients. When this is not maintained, it often shows through the hair becoming drier, coarser, less elastic and harder to manage. This is why scalp condition plays such an important role in how hair looks and feels over time.
Developed in Korea, this formulation is part of a Double Anti-Aging Clinical Trial for both scalp and hair, supported by 13 completed clinical tests at OATC Skin Clinical Trial Center. Rather than focusing only on cleansing, the approach is to support scalp balance and maintain a healthier environment for hair over time.
The formula is built on SMiB’s proprietary SP-3 Complex (30,000 ppm) together with skincare grade ingredients such as niacinamide, panthenol, peptides and botanical extracts. These ingredients are selected to support scalp vitality, maintain moisture balance and care for the scalp as collagen naturally declines.
Using a gentle coconut derived cleansing base free from SLS and SLES, the shampoo cleanses without over-stripping, making it suitable for consistent, everyday use.
With regular use, maintaining a healthy scalp environment allows hair to appear youthful, smoother, more manageable and naturally healthier over time. We’ve seen this reflected not just in testing, but in real, long term users of the Herb Spa series

Your product is amazing! This is the difference after only 1 wash. Plus I have very sensitive skin and I didn’t have any adverse reactions. I am speechless. Thank you SMiB!

The grey hairs are visibly gone and they become dark brown after 4 weeks. I prefer this way than dying my hair with chemicals

I hope my review can help someone who looking on the shampoo. I had used the shampoo for one month and below is the result:- 1. Herb Shampoo: A. Scalp redness: I have been suffering from scalp redness (sensitive) for many years. This shampoo does help me to reduce the redness slightly (Note: but not totally remove it). B. Itchiness: The shampoo did help me soothes the itchiness. It can see significant result. C. Hair Growth: Monitoring still in progress as i only using 1 month. So far there is no significant hair growth yet. The number of hair fall also still at monitoring. Although the number of hair fall can observed significant reduce when I am using hair dryer, but It doesn't mean the hair fall is really reduce. (Note: Hair fall might happen when we shampoo). It should refer back to the 50X scope i provided in the video. Scalp build up: Per 50x Scope, Scalp built up still remain on the hair after 1 month of shampoo. Not sure the Coral treatment can help it or not, as it contain salicylic acid. Overall Comment for herb shampoo: Very comfortable, there is lot bubble. Shampoo is gentle and did better to help me reduce slightly on redness when i combine this herb shampoo with Aveda Nuit Serum (Note: result is compare with using Aveda Balancing Shampoo+ Conditioner+Nuit Serum). Will update the hair fall result again if the update at here still available after the comment. You may reach me through email (jotdxabt@gmail.com) to ask the hair fall result after 6 months of usage if the review here cannot be updated anymore. Thinking whether to try the coral treatment to replace Aveda Serum Nuit in the next. Not sure will it further help me reduce scalp redness, scalp built up and hair fall issue. 2. Color change shampoo This shampoo color your hair to become black. The result can see immediately after one time use. As it's natural product, I strong recommend to replace your chemical hair dye with this shampoo. The price is not cheap for Malaysian. Hopefully my review will help you.

I am amazed by this colour change shampoo and it is able to cover my grey hair. I used to go salon touch up my roots every 1.5 months and now I solely rely on this without having the need to go to the salon. I realised not only can I cover my grey and it actually smoothen my hair. A before and after picture and the below photo showing after using colour change shampoo. I don't rely on the colour change shampoo and will switch back to my usual shampoo Herb Spa after I get my coverage. A picture speaks a thousand words, seeing is believing and it really works for me!

My grey hair usually grow one month after I coloured my hair. I started using this product in September 2026, and I noticed that the product could cover my grey hair.

SMiB Anti-Aging Series - Herb Spa Shampoo - Vegan | Scalp First | NO SLS / NO SLES
This is my first try on the color change shampoo. I chose my favourite brow n. I simply love it since it covers grey hair well. I started using it on alternate days, followed by weekly and now I use it bi-weekly. No more dying of hair required. This is straightforward to use and for color maintenance since shampooing is my daily activity. However, hair may feel a bit dry after wash, so conditioning is recommended.

I hv been using for a few months. I change back to black colour for better coverage and find the hair shampoo is much softer than brown. Its would be ideal if you can come out with small travelling pack for easier packing during our holiday

The herbal Anti-aging shampoo really helps to cleanse your scalp and you will feels refresh after using it. In additional, you can use it daily without fearing that it is too strong for your scalp. After using it, pair with the scalp essence to make it even stronger. Definitely recommended.

I have used 6 times so far, one time was directly applied to my dry hair for 15 min. This shampoo was not really foamy type as per what was advertised. I tried once to wash my hair with normal shampoo follow by using this colour changing shampoo then will get a bit of foam. But so far it did gradually cover some of my grey hairs. Will stop for now and will use it when my grey hairs grow out again.

I started using this shampoo 2 or 3 years ago. I have sensitive scalp which often results in redness on my scalp. But since using this anti-ageing shampoo, the redness has gone. However, the itchiness has remained but very much lessened. I have confidence in this shampoo and will continue using it as I know it contains free of chemical and will not harm my scalp.

[SMiB] - Women’s Day Flash Sale! Color Change Shampoo - Vegan Certified
I leave it for 10-15 mins before I wash it off. I like that it provides gloss after I use it for touch up on my roots. It’s soft as well: but be careful it will dye your face and nails. So I wore gloves and also apply some olive oil on face area before I leave on. But overall, I will purchase again. Note: it states natural brown but it is rather dark

I have been using your Herbs Essential for more than a year now. I have switched from the Innabi shampoo to the Herbs Essential because I have sensitive scalp and find that scalp inflammation and itchiness had lessens as well as hair loss. Have seen hair drop lessens during shampoo and Treatment. Have not started on the Color Change yet but will do so when more grey hair appears. 😁
