Yes you read correctly, beer is good for your curly hair. The benefits of a beer rinse are softer hair, shine, volume/bounce and revitalizes curls. Buy hair volume enhancement, to get the volume you are looking for. I wondered if this would be good for my 3a/3b low porosity curly hair. I decided to give it a try.
What you need is a bottle of beer. It is recommended that the beer be non-alcoholic. Non-alcoholic beer is more acidic so you get the best results. I didn’t use non-alcoholic beer because I didn’t want to invest in a 6 pack that cost $8. I had a bottle already that I could use and it wouldn’t cost me a thing. The beer should be room temperature and flat. So just open it and leave it out overnight.
I decided to wash my hair in the sink because I wasn’t down with the idea of a whole body beer bath.
I started off by cleansing my hair with NYC Curls by Carlos Flores. I took the opportunity to detangle my hair at this point.
Next I poured out the beer into a measuring cup to make it easier to pour. I placed a large pot in the sink to catch the beer as it fell off my hair. I would pour back the beer into the cup and pour it on my hair again. I did this about 4 times making sure to really saturate my hair. I scrunched my hair several times working the beer into my hair. I would say this process might have lasted about 5 minutes. During this rinsing process my hair felt soft. I rinsed out the beer with plenty of warm water. My hair had a faint beer smell. 
The last step was to condition my hair. This step is optional. Some people do it and others don’t. But it does help eliminate the beer smell if the water rinse didn’t do it. I conditioned my hair with EO Essentials lavender & aloe conditioner mixed with two spoons of honey. I saturated my hair with the mix and combed it through. I then rinsed with warm water.
I styled my hair as usual. My hair was super soft. I had a lot of volume in my curls and at the top as well. I did notice a bit of frizz at the top but it wasn’t too bad. My hair was very shinny and my curls did look more tightly coiled. I am very impressed with how this rinse worked out for me. If the results were good with regular beer I can only imagine they will be even better with the non-alcoholic beer. I will definitely be investing in getting some non-alcoholic beer to do this again on my hair.
I give beer rinses for 3a/3b curly hair 5 brains.
