I started only taking them every 3-4mths but at the end of last year I was taking them monthly because I was in a 3inches challenge. Now I thinking I will check maybe 2-3mths in between stretch and when I texlax.
I am doing length checks every 3-4months, which is everytime I take down an install. Once my hair reaches MBL(which should be June 2010.) Then I will do a length check every two months(more often because after I hit MBL I plan to retire my weave hair, so my hair will be more accesible to do length checks, yaay!) After my hair is grazing WL I will probably barely ever do an official length check.
My last length check was early November I wanna say which was my last relaxer. My next relaxer will be this Thursday and I will do a length check. Hoping for full BSL and then MBL in late May .
I do a length check like every time I get a perm which is every 3 to 4 months. But now I'm trying to go longer than 6 months with protective styles, like braids, weaves. I'm already 15 weeks post.
I do a formal length check after every relaxer, because that usually the only time my hair is straight! LOL I take pics every month but since its usually curly or wavy, I dont compare them
I do a length check when I get a relaxer every three months.
However, I did take a length shot last week on Feb. 6 (even with 8 wks of ng and curled up ends) because I just had to get a picture one year to the day that I took my very first hair pic.
