Determining porosity

I am still so confused as to whether my hair has low or normal porosity. I put a strand of hair in a bowl of water, and it just floats on top. Does this mean my hair has low porosity or normal porosity?

Also, my hair feels smooth when I grasp it and slide my fingers along it up and down.

My hair tends to get frizzy on humid days and stays flat on dry days.

My hair has also been colored and high-lighted for years - does this affect it?

I just can't figure it out.

Hair Type - wavy/curly, fine texture, thin/medium density

Hi,

If your hair strand floats in water and it is smooth when you do the finger test, then you are probably low porosity. However, if you have had coloring and highlights for years then the hair may be somewhat damaged and probably has some raised cuticles and damages spots like those who have coarse hair and high porosity, even if you didn't feel them. This damage to the hair may be why your hair gets frizzy. You will need to do a protein treatment to repair the damage. Follow the protein treatment with a moisture treatment. You can do this once a week until your hair looks better.

Now it is also possible that you simply have fine, low porous hair that is dry. In this case, you could use some protein and lots of moisture.

This is from livecurlylivefree.com. You can use this to finally help you determine.

Low Porosity
Low porosity is when the cuticle of the hair shaft is too compact and does not permit moisture to enter or leave the hair shaft. Hair with low porosity is much more difficult to process, is resistant to chemical services, and has a tendency to repel product rather than absorb it.

Normal Porosity
With normal porosity, the cuticle is compact and inhibits moisture from leaving or entering the hair shaft; however, it allows for normal processing when a chemical service is performed and will readily absorb and retain product properly formulated for this hair type.

I hope this helps.

belasuna,

Yes, that helps a lot. Thank you for the info.

I'm going to try a protein and some more moisture products.
