What works, what does not, and the scalp-first routine that helps
Short answer: there is no shampoo that regrows hair. Hair regrowth comes from evidence based treatments such as minoxidil and from addressing causes like iron deficiency or thyroid issues with your doctor.
Shampoos can still help in two important ways:
- Keep the scalp healthy and calm, which can reduce excess shedding from dandruff or irritation.
- Remove film and residue so hair looks fuller and breaks less.
Below is a clear guide to what shampoo can and cannot do for hair loss, plus three supportive cleansers that make a visible difference to fullness and scalp comfort. For product level picks that focus on visible fullness rather than regrowth, see our companion guide Best Shampoo for Thinning Hair.

What shampoo can and cannot do for hair loss
Can help
- Reduce flake and itch that trigger inflammation and more shedding
- Keep follicles clear of heavy oils, silicones and styling residue
- Add cosmetic thickening so hair looks fuller today
- Support a topical routine by leaving the scalp clean and calm
Cannot help
- Regrow hair or stop genetic androgenetic alopecia. That needs minoxidil or a medical plan set by your clinician.
- Reverse scarring alopecias. These need fast specialist care.
If your shedding is sudden, patchy, or comes with scalp pain, see a GP or dermatologist.
Who this guide is for
- You see more hair than usual in the brush or shower but you also deal with oily or flaky scalp, product build up, or hair that feels flat.
- You want products that help hair look fuller and support a treatment plan even though they do not regrow hair.
Who should skip straight to medical care
- Sudden or patchy loss, a burning or tender scalp, visible scarring, or shedding that lasts longer than three months.
- Postpartum shedding that feels extreme or persistent.
- Any concern about iron, B12, vitamin D or thyroid. Ask for blood tests.
The supportive picks
1) Nizoral A-D, 1 percent ketoconazole
What it is: An over-the-counter dandruff shampoo that targets Malassezia yeast with ketoconazole.
Why it helps: Less flake and itch means less inflammation and less breakage from scratching. Keeping the scalp calm helps you stick to a growth treatment like minoxidil.
Use it like this: Two to three times per week. Lather, then leave on the scalp for 3 to 5 minutes before rinsing. On off days, use a gentle cleanser.
Pros: Clinically backed active, fast itch relief, visible flake reduction.
Cons: Can be drying on lengths. Condition mid-lengths to ends only.
Rating: 4.6/5.
2) Briogeo Destined For Density Caffeine + Biotin Volumizing
What it is: A light, silicone free cleanser with maltodextrin and caffeine for root lift.
Why it helps: Removes film that makes hair clump and lie flat. Hair looks thicker and bouncier after one wash.
Use it like this: Emulsify with water, massage the scalp for 60 to 90 seconds, then rinse. Double cleanse after heavy stylers.
Pros: Instant body without stiffness, colour safe, good daily option.
Cons: Not a dandruff treatment. Pair with a scalp day if you are flaky.
Rating: 4.7/5.
3) Neutrogena Anti-Residue Shampoo
What it is: A simple weekly clarifier that strips stubborn build up.
Why it helps: Residue from oils, dry shampoo and hard water can make hair look limp. A weekly reset keeps your daily shampoo effective.
Use it like this: Once per week only. Follow with a light conditioner on lengths.
Pros: Cheap, does the job, improves the feel of all your other products.
Cons: Overuse can feel drying. Keep it weekly.
Rating: 4.5/5.
Build the routine
- Scalp first. Massage shampoo at the scalp for 60 to 90 seconds.
- Lengths second. Pull suds through ends for the last 10 seconds only.
- Anti-dandruff rhythm. Use Nizoral A-D two to three times per week until flakes settle, then reduce as needed.
- Weekly reset. Clarify once per week if you use oils, dry shampoo or hairspray.
- Style light. Use a heat protectant and avoid heavy oils at the root.
- Evidence based growth. Apply minoxidil to a dry scalp after washing. Be consistent and give it at least three months.
Wrap-Up

FAQ
Do shampoos regrow hair
No. They support scalp comfort and the look of fullness. Regrowth needs treatments such as minoxidil or a medical plan.
Is ketoconazole a hair growth treatment
No. It is an anti-dandruff active. It can reduce inflammation and flake which can reduce excess shedding.
How long until I notice a difference
A fuller look is immediate after a good cleanse. Scalp comfort improves within one to two weeks with consistent use.
Can I use anti-dandruff shampoo every day
Follow the label. Many are two to three times per week. Use a gentle volumising shampoo on other days.
What ingredients should I avoid
Very heavy waxes and butters at the root. If you love oils or stylers, keep the weekly clarifier in your plan.
