Anyways I'll be teaching you how to do the test today.

To do a hair porosity test, you have to make sure your hair is clean meaning you'd have to wash and dry the hair first, do not apply any cream or oil, and if you do not want to wash your whole hair it's fine. Since all you'll be needing is a strand of hair, you can choose to wash just that one strand and dry with a towel.

Get a glass filled with water and drop your hair into the water. If your hair floats on the water it simply means you have low porosity hair,(your hair finds it hard to absorb moisture,) so you'd have to avoid products with protein in them and always use warm water to wash your hair, it'll help you open the pores on your scalp.

If the hair sinks to the bottom of the cup then you have a high porosity hair. Feel free to use any good product on your hair. 

And lastly if the hair stats in the middle then you have normal porosity, therefore anygood products can work.

For those of you with low porosity hair you can try out mielle rosemary mint products or mielle pomegranate and honey collection they have zero protein in them

If you have high or normal just any good product can work

Whatever porosity you have,just be consistent with your haircare routine and you'll definitely see results

Lastly,try not to over oil your hair. Oiling at least once a week is enough.

Do not comb your hair dry and make sure you wash often.

Do remember to cut off split ends, do not be scared to lose that part of your hair cause you're better off without them.
