OP, I feel your frustration as far as trasitioning during a deployment, I dud it while I was deployed to Iraq and then did the BC while I was there after only a few months into my transition with a significant amount of growth. Since you are on a ship and I was on land, I'm not sure how it will be as far as receiving packages and ordering things online but you always have that option so don't worry if you don't get everything before you go. How far into your transition are you and how much relaxed bs new growth do you have? If your hair is currently like your profile pic then, microbraids or twists could be the way to go initially so your scalp can breathe and you can get to it to oil it and stuff. Also you can take out sections and redo it so they stat looking fresh, which is what I did on my deployments... I know how to braid and whatnot so if you don't know how, you can check your bucket and see if there is anyone deploying with you who can do this for you. If not, then at least you have 2-3 months of a braided style, depending on your hair growth. Also you can get a few foney ponys to attach to your ponytail.... You can braid it in the front and attach the pony onto yours.
Www.goldenmartbeautysupply.com has an amazing selection for just about everything, they ship to APO,AEO etc, addresses and they are fast... If you can braid, seeing as you are on a ship, you can make extra cash by doing other girls hair as well, that's what I did. It worked out well, I didn't have to really spend any of the money I was making.... Lol otherwise, i definately agree with the others, a good sulfate free shampoo, moisturizer, conditioner, wide tooth comb, rat tail comb, shears ( you may not want to BC yet but in case you develope split ends, you want to nip them in the bud, literally)stock up on the seamless ponytail holders or learn to make one with a stocking, at Sallys there is a cap that acts somewhat like a steamer and locks in moisture, because you will be on the ocean and idk how the conditions of your ship will be that may be a good thing to get, it's only a few bucks for a set of 4. Do you know if the showers have hard or soft water? If you could find out, that may save you a world of headache... If I can think of anything else, I'll let you know but good luck and God bless,
