Take Back Your Hair Health Using This Simple Routine
This routine is for everyone—whether you’re addressing hair shedding and thinning or proactively maintaining the health of your hair. With consistent care and premium ingredients, you can protect your hair follicles, promote growth, and ensure long-term vibrancy and strength.
Step 1: Cleanse with Care
Begin by thoroughly wetting your hair with warm water to loosen buildup and prepare your scalp for optimal cleansing. Massage Adegen ARB™ Shampoo into your scalp, allowing its premium formula to remove dirt, dandruff, and pore-clogging sebum. This step creates the ideal foundation for healthier, thicker hair.
Step 2: Exfoliate & Boost Circulation
Stimulate your scalp and unlock the full potential of your shampoo. Using the SM Brush, vigorously exfoliate your scalp to remove buildup and dead skin while increasing blood flow to thinning areas. This step helps deliver nutrients deep into your follicles. For best results, let the shampoo sit for 5 minutes to allow its active ingredients to penetrate fully.
Step 3: Rinse & Revitalize
Rinse out the shampoo thoroughly, letting the eucalyptus refresh and invigorate your scalp. With every use, you’re not just cleansing—you’re laying the foundation for long-term follicle health and stronger, more vibrant hair.

What is ARB Shampoo and how does it work?
Our ARB Shampoo is a clinically formulated shampoo designed to support scalp health, promote thicker, fuller hair, and reduce hair shedding. It works by cleansing the scalp, removing buildup, and nourishing hair follicles with key ingredients that support hair regrowth and strength.
Who should use ARB Shampoo?
Our ARB Shampoo is ideal for anyone experiencing hair thinning, excessive shedding, or looking to maintain a healthy scalp and stronger hair. It is suitable for both men and women.
What ingredients are in ARB Shampoo?
Our ARB Shampoo contains a blend of scientifically-backed ingredients, including:
Purified water, purified water sodium laureth sulfate, caffeine, PEG-120 methyl glucose dioleate, disodium laureth sulfosuccinate, laureth-2, sodium lauroyl glutamate, panthenol, zinc PCA, menthol, sodium chloride, phenoxyethanol, hydrolyzed wheat protein, eucalyptus globulus leaf oil, PEG-40 hydrogenated castor oil, melaleuca alternifolia (tea tree) leaf oil, citric acid, chlorphenesin, niacinamide, potassium sorbate, sodium benzoate, lauric acid/sodium laurate, polyquaternium-10, sodium glutamate, disodium EDTA, tocopherol.
How long can I expect to notice results?
From the very first wash, our ARB Shampoo begins working to cleanse your scalp, remove buildup, and create the ideal environment for healthy hair growth. Many users report feeling a cooling, refreshing sensation and noticing improved scalp cleanliness and reduced oiliness immediately.
Within a few weeks, you may experience stronger, healthier-feeling hair with less breakage. However, for those experiencing hair thinning or shedding, visible changes in hair density typically take 3-6 months of consistent use.
It's important to note that some initial shedding is normal as weaker hairs are replaced with healthier, stronger ones. This is a natural part of the hair renewal process and should stabilize over time. For best results, we recommend using ARB Shampoo regularly as part of a complete hair care routine, including our scalp massage brushes.

- ETErica T.Verified BuyerRated 5 out of 5 stars7 months agoBest shampoo I’ve ever used
This is the only shampoo I’ve ever used that gives my hair volume. When I first started using this product I washed my hair everyday as it instructs. I started using this shampoo in January 2024. About a month later and still to this day I use it about 3-4 times a week. I have long hair and it was hard to manage washing and styling my hair 7 days a week. Every time I use the shampoo I use the scalp stimulator brushes and leave it on 10min. I never use conditioner anymore and my hair is great. I used to loose handfuls of hair in the shower, now I loose 5 strands max.
- JSJames S.Verified BuyerRated 4 out of 5 stars8 months ago3 months progress
It's hard to tell whether the topical or shampoo is having the most impact but together with the scalp brushes and micro-needle roller I'm making really good progress. My hair is thicker and softer than it had been in years. I'm hoping my parking lots begin to fill in but from what I've read if the hair follicle is dead, a hair transplant is the only solution....and that is off the table. I'm so grateful to Adegen for the obvious improvement I've made so far. Patience and consistency is the name of the game.

Hi everyone,
It’s been about a year and a half since I started using the shampoo and brush only. I shampoo every other day and brush twice everyday. Thought I would show you what my hair looks like today vs before I started. The first pic was pretty much my hair at its worst. These are both shown after I comb it and spray gel it right out of the shower. Also adding a pic of how it normally looks dry now.
- ACAustin C.Verified BuyerRated 5 out of 5 stars3 years ago5 Stars
So I wanted to share with you guys my progress. I’ve only been using this for three weeks. I immediately start with the 15 topical drops instead of the 5. Why not go all the way the first time was my thought.
My routine as follows: before I go to bed
Wash my hair with the shampoo and use the brush for 5 mins. Then wash my hair off. And then I reapply more shampoo and let it set for 10 mins and then wash off. Then I use 2 MLs of the dropper and let that sit on my head all night and then all day the following day and then repeat. Every other day a use the roller for 5 mins
I did get a hair transplant about 5 years ago and I would never recommend it too anyone ever. Super painful and expensive. I wish I would have know about adegen back then because I wouldn’t have put myself through that.

Black t shirt = today
Can’t believe this so only 90 days and my hair is sooooooo much thicker with loooooads of new hair growing! So so happy with my progress and can’t wait to see how things develop!! This stuff is magic!!
I started with shampoo and 5s but once the bottle of serum was finished I just continued with shampoo, and seems to have some the trick.
