Keep reading this article to get the best shampoo advice and find out more about:
Some hair loss is normal in the shower, but if you are shedding more than 50-100 hairs per day, it may be a sign of diffuse thinning. If you are experiencing this, it is very important to choose the right shampoo.
Using a blend of research and expertise, we have put together a list of the best 9 kinds of shampoos to use for alleviating your hair loss.
Warning: Before using any of these products, it is a good idea to consult a hair specialist. That is because, in a small proportion of users, some of them can have paradoxical unwanted side effects, such as causing hair loss instead of treating it.
Ketoconazole (KCZ) is a substance which is highly effective in reducing dandruff and seborrheic dermatitis . But it may also have anti-inflammatory properties which inhibit hair follicle miniaturisation .
A study  was conducted on 39 men with Norwood scale stage 3 male pattern baldness, some of whom were treated with topical Minoxidil and others with a 2% KCZ shampoo.
Results showed that the relationship between ketoconazole and hair loss was promising, as ketoconazole shampoo had an unquestionable effect on hair density, size and proportion of anagen follicles, to a very similar extent as Minoxidil 2%, which is one of the most recommended hair growth treatments.
A further clinical trial  on 176 patients also revealed an 80% improvement in dandruff after 4 weeks of use.
Recommended Ketoconazole shampoo brand: Nizoral 2%
Zinc pyrithione in shampoo form is known for keeping your scalp clean and healthy, reducing dandruff and preventing hair loss, with low chances of causing irritation.
Research indicates that this medicated shampoo can also be effective in the treatment of scalp psoriasis, alongside topical corticosteroids

Stemoxydine for hair loss is an antioxidant which has been shown by research to decrease the proportion of hair which is in the telogen (shedding) phase, and thus reduce the proportion of your hair falling out .

Caffeine can do more for you than just wake you up in the morning: it can also stimulate your hair growth. Caffeine shampoo for hair loss is efficient on its own, but even more so when it joins forces with zinc and niacin to form phyto-caffeine.
Research performed on women with female pattern baldness revealed that after 6 months of regular phyto-caffeine shampoo use, subjects showed significant improvements in a hair pull test .

Rosemary oil is one of the best essential oils for hair growth. A study performed on 100 patients with male pattern baldness revealed that rosemary oil for hair growth is just as effective as Minoxidil when it comes to increasing hair count after 6 months of regular use .
While there aren’t extensive studies on this, some scholars believe that rosemary is effective in reducing dandruff and hair greasiness in shampoo form .

Shampoos are normally safe to use and should not make your hair fall out. However, some of them contain harsher or more health-hazardous chemicals than others, which should be avoided by people who are already experiencing signs of hair thinning.
So when choosing a shampoo, you may want to check the ingredient list and stay away from the following hair products:
These cleaning agents act like powerful detergents, eliminating all sebum and debris on your scalp. But in the process, they can be too harsh on your tresses, leaving you with dry, brittle hair which breaks easily.
Antifungal and antimicrobial agents, parabens have been revealed to cause hormonal imbalances and have even been connected to breast cancer .
Formaldehyde is a preservative which can be highly toxic and lead to a number of serious health issues 
While this compound has preservative and antimicrobial properties, it also releases formaldehyde into your hair, damaging it.
Used as thickening agents, alcohols such as propanol can leave you with dry, brittle hair.
This compound relieves itchiness and dry skin caused by dandruff. Sadly, it is also likely to be a carcinogen .
This type of silicone makes your hair feel silky, but it can leave you with a dry, irritated scalp.
While salt is not inherently bad for your health, when used as a thickening agent in shampoo, it can make your scalp dry and itchy.
These gelling compounds are known to cause significant endocrine, reproductive, developmental and neurological health problems  and are also damaging to the environment.
There can be multiple conditions which could be responsible for your hair falling out. The most common of these include:
It is important to get an accurate diagnosis for your hair loss as soon as possible, so you can receive the most appropriate treatment and keep your condition from becoming worse. That is why you should book a consultation with a trichologist.
They will use minimally invasive procedures, such as dermoscopies or blood tests for hair loss, to pinpoint the exact cause and nature of your shedding and provide you with the best hair loss treatment.
The best treatment for your hair loss depends on the reason why you are experiencing it. While shampoos may alleviate the symptoms of milder forms of balding if your shedding is more advanced, a stronger therapeutic approach may be required.
