18 best hair-loss shampoos to promote growth, tested by 700 people
Revive thinning hair during menopause and beyond

A good hair day can boost your mood like nothing else. Equally, dealing with hair loss or thinning hair can have a real impact on your confidence.
If you start to notice your hair thinning or falling out at a faster rate, it could be down to a number of reasons, from damage caused by heat styling to fluctuating hormones, but, thankfully, the best hair loss shampoos are designed to help.
But, it can be hard to know if all those claims actually stand up. So, with the help of our reader panel, the Good Housekeeping Institute experts tested a range of shampoos (and their conditioner counterparts) for thinning hair to find the ones that will help reduce breakage, add volume and stimulate the root and scalp to promote healthy hair growth.

These are our experts' top picks for thicker, healthier tresses at a glance, but read on for everything you need to know about hair thinning, along with our detailed reviews.
What causes female hair loss?
Shedding hair is normal and usually nothing to worry about — according to the NHS, we can lose between 50 and 100 hairs a day on average. For women, more excessive hair loss can be caused by a range of factors, including hormonal changes (such as when you’re pregnant or going through the menopause), ageing, a diet lacking in nutrients, stress, iron deficiency, or as a side effect to an illness or treatment.
Being overzealous with heating tools and years of bleaching can also play a part in hair loss, especially around the hairline. Both contribute to breakage by making hair more dry and brittle, eventually leading to hair fallout.
Can shampoos really regrow hair?
Technically, shampoos can’t regrow any missing patches of hair. However, what they can do is create the right environment to encourage healthy hair growth.
Keeping your scalp clean and healthy is key to achieving a fuller head of hair. Ingredients to look out for range from caffeine to peppermint oil, which can help boost circulation, while proteins and keratin will help strengthen hair and give it more resilience.
Hair loss shampoos and conditioners are formulated to target the common causes of hair loss. These are the main types:
- Anti-breakage shampoos and conditioners: these reinforce the structure of the hair strand, aiming to prevent breakage and splitting.
- Hair-thickening shampoos and conditioners: these focus on making hair appear (and sometimes feel) thicker by creating more body and lift.
- Root- or scalp-stimulating shampoos and conditioners: these aim to clear away root or scalp build-up and stimulate the hair follicles to encourage healthy hair growth.
How we test hair loss shampoos
We gave 700 testers — all with self-diagnosed mild to extreme hair loss or thinning and with a range of hair types, from straight to afro — a shampoo and conditioner set to trial for between one and two months.
The products all claimed to correct one of the three main causes of hair loss: anti-breakage, hair-thickening and root- or scalp-stimulation. After the trial period, our panellists gave us detailed feedback on the products, noting any differences they saw in their scalp and hair condition over the trial period and how their hair felt after each wash, as well as reviewing packaging design, ease of use, texture and scent.
In the Good Housekeeping Institute beauty lab, we assessed anti-breakage shampoos by combing through hair switches that had been treated with the product and comparing them to untreated ones. The easier the treated switches were to comb, the less risk of hair breakage and fall out in real life.
To assess the efficacy of thickening and root-stimulating shampoos, we used our specialist Hair Metrix machine to analyse the effect each formula had on hair density and thickness.
