I so wanted to answer your post in more detail, but my body just wouldn't let my hands type. /images/graemlins/grin.gif I'm so so tired!!
Anyways YES you can use it to chart for your braids progress. You can create a section for hairstyles worn and chart your hair in this way on the sheet to see exactly how long you wear your hair in braids for, compared to how often you wash them etc. I chart my same ponytail hairstyle on the sheet daily.#
If in a years time someone wants to know how I grew my hair out they can refer to it and see that the protective style contributed to the hair growth as one factor as well as all the products I've used.
This has been a great deal of help to me, as I never coloured in my sqaures on the sheet. If I never wrote it down on a piece of paper I wouldn't even be able to have remembered what supplements I took or hair products I used only 2 days ago. Lord know I wouldn't be able to remember in 1 years time, if someone asked me excatly what I used on my hair journey /images/graemlins/nono.gif
