#Hair loss shampoos: do they work, how do they work and the best shampoos available
With so many anti-hair loss treatments available, it can be tough to make a decision.
In this guide we showcase the best hair loss shampoos, how they compare to normal shampoo and the ingredients to look out for.
In this guide
Ingredients to look for in hair loss shampoo
Zinc
Zinc is an essential mineral for your body.
Your body uses zinc for many different functions such as:
your immune system
healing wounds
physical growth
taste and smell
The issue is that your body doesn’t store zinc, and so needs to be continually refilled to keep these functions active.
You can find zinc in foods such as meat, fish, dairy and nuts.
However, according to Medical News Today, about 1.1 billion people on earth are zinc-deficient.
Hair loss can be directly linked to zinc deficiency, and is one of the key indicators of severely low levels of the mineral.
To combat this, hair loss shampoos use zinc as an ingredient.
How does it help?
Not only does zinc deficiency lead to hair loss, but zinc also plays a crucial role in producing DbvNA and RNA.
This is needed if your hair follicle cells are to divide normally, and for your hair to remain healthy.
Biotin
Biotin is a B vitamin found naturally in egg yolk, liver and yeast.
In regards to hair health, biotin improves your body’s keratin infrastructure.
Keratin is one of a naturally occurring family of fibrous proteins that are key to the structural make-up of hair.
How does it help?
According to a study conducted by The Journal of Clinical and Aesthetic Dermatology:
“The daily administration of a proprietary nutritional supplement significantly increased hair growth after 90 and 180 days.
Self-perceived improvements after 90 days were increased after 180 days of additional treatment, suggesting continued improvements may occur with ongoing treatment.
No adverse events were reported.”
Basically, biotin definitely helps hair growth.
Not only that, but improvements increase the longer you use the product.
Niacin
Niacin is another name for nicotinic acid.
It’s an organic compound and a form of vitamin B3, which is an essential human nutrient.
It can improve blood circulation, which then carries more oxygen and nutrients into the hair follicles.
How does it help?
A six-month study found that niacin led to significantly fuller hair on women with female pattern baldness.
The researchers stated that:
“Long-term topical application of nicotinic acid derivatives offers promise for providing benefit in female alopecia.”
However, this was only a small-scale pilot study, and so could easily be disproved further down the line.
For now, it’s showing promise and warrants further investigation.
Keratin
As previously mentioned, keratin is a natural protein and one of the main materials in hair, making up 90% of your hair strands.
It forms a protective shield around the hair follicles to keep your hair looking thick and healthy.
How does it help?
Professional hair stylists can add extra keratin to your hair by applying special keratin treatments.
These are designed to strengthen the hair, which could help slow the hair loss process, although this isn’t proven to work.
Keratin shampoo is also available to buy over the counter.
Although keratin hasn’t been proven to stop hair loss, it’s a key ingredient due to the level of protection it offers.
The fact that the family of keratin proteins makes up 90% of your hair shows that it’s important for general hair health.
Do hair loss shampoos work?
Unfortunately, it’s not a simple yes or no answer.
Many hair loss shampoos contain the ingredients mentioned above—zinc, biotin, niacin and keratin—which scientists have tested and found to work.
However, there hasn’t been a wide enough study to find a single product that 100% cures hair loss.
Part of this can also be attributed to a variety of issues that cause hair loss.
A hair loss product that tackles male pattern baldness will not help people who suffer from a zinc deficiency.
The wide range of causes means it’s hard for scientists to claim that a product cures all types of hair loss.
Often their tests are smaller studies focusing on certain issues such as alopecia and male pattern baldness.
