Can bananas block dht? 

Yes bananas are packed with numerous vitamins minerals lycopene and some researchers feel that they they can block dht. 

Basically bananas are fantastic for overall health and well-being and they're rich in vitamins b6 and b12 as well as magnesium and potassium they also contain protein and fiber bananas are also rich in a plant nutrient that has lots of antioxidant properties and I've mentioned this nutrient before it's called lycopene now lycopene helps to block dht and it helps to inhibit hair follicle and skin sensitivity to dht.
Dihydrotestosterone is the male androgen hormone which is responsible for lots of the heavy lifting of male puberty so for example it's responsible for maturation of the penis and a deeper voice and body hair two-thirds of all men worldwide have a hair follicle sensitivity to dihydrotestosterone so in certain places on their scalp their hair follicles are more sensitive to the effects of dihydrotestosterone dht attaches itself to hair follicles and shrinks them in a process called

Miniaturization and this is what leads to male pattern baldness and so eating certain foods and having certain drinks and snacks can really reduce dht hair follicle sensitivity because less dht is floating around your system because these foods and drinks and snacks are soaking them all up and inhibiting dht. 
 I'm gonna put a link  in here to a previous video because if you're interested in this topic I’ve done an entire playlist all about the best foods drinks and snacks to block dht hair follicle scrubs that you can do exfoliant scrubs and things you can eat and drink everything really hair oils that you you can use to block dht and they're all homemade and natural.
 Bananas are also rich in magnesium and magnesium is really useful for healthy hair growth in a number of ways magnesium helps to prevent calcium buildup on the scalp when calcium clogs up your hair follicles it can make your scalp dry and flaky and can make your hair brittle and dry and fall out and so by preventing magnesium buildup it's fantastic for healthy hair growth and so preventing calcium buildup it's fantastic for healthy hair growth magnesium also helps in building protein and so you might already know that hair is made up of a rough protein called keratin and so magnesium really helps protein to synthesize and to keep your hair healthy and strong bananas are also a great source of Biotin
Biotin is a B vitamin that some studies have found helps in encouraging normal healthy hair growth and certain studies have also found that biotin can help speed up hair growth bananas are also incredibly rich in potassium and this nutrient helps to encourage a normal healthy circulation.
When your circulation is healthy it means all the vitamins and minerals from the foods that you're eating and the drinks that you're having make it are making their way towards your scalp and nourishing your scalp and encouraging normal healthy hair growth which is what we want they also contain Fructooligosaccharides  that help to reduce dht overproduction.
Bananas can also be applied topically to your scalp as a fantastic hair mask and hair growth treatment  combine bananas with coconut oil, olive oil you can also  combine them with eggs.
 
Bananas can also help to support a healthy gut bananas are a low fructose fruit that are fiber rich and contain something called inulin which is a substance that stimulates the growth of good bacteria in the gut and a healthy gut environment and lower levels of unhealthy bacteria in the gut have been shown to help maintain normal levels of dht.
I also wanted to mention a few other handy foods that can help to block dht:
Eggs are rich in biotin they help to encourage normal healthy hair growth and healthy circulation they're also packed with numerous vitamins and minerals.
That encourage a normal healthy scalp.
Tomatoes I've already mentioned lycopene tomatoes are extremely rich in the nutrient lycopene which helps to block dht and the best source of lycopene is actually processed tomatoes for example processed pasta sauces that you get in jars at the shop or processed tin plum tomatoes these are great sources of lycopene.
Avocados, they're high in proteins amino acids folic acids magnesium copper and iron avocados help to block  dht and encourage normal healthy hair growth walnuts walnuts contain l-lysine which is a natural dht blocker they're also extremely high in protein and vitamin e
