Sisterly Advice: Keeping Natural Hair Moisturized in the Winter

One of my sisters, who's in college in Boston, called me not to long ago telling me that she wanted to deviate from her "box-braids routine" and wear her hair "out" for a little while and wanted to know what products she could use to keep her hair moisturized. I'm always excited when one of my sisters or cousins (and even my fiance's relatives) call to ask me what they should do or use on their hair, makes me feel like I may be doing something right with my haircare. I especially feel pleased when this particular sister calls me about hair stuff because I'm the one who convinced her not to ever relax it and promised I'd show her how to "rock what she got"-which is how I became interested in blogging about hair in the first place!

Anyway, I texted her a basic answer so that she could refer back to it later and then I thought I should also post about it, because it might help other inquiring minds. So again, the question is: How Can I keep My Hair Moisturized in the Winter? What Products Should I Use?
My Answer: To keep your hair from drying out, it's not just having the right product but the art of sealing your hair. This basically involves using a water-based product (ex. conditioner), and locking in the moisture with an oil (ex. coconut) or butter (ex. shea).

My sister also expressed not wanting to have to wet her hair everyday for moisture - after all it's winter time and no one wants to walk outside with wet hair. I recommended that she spritz her hair as needed with a home made mixture (in her case, she's always been good with Extra-Virgin Olive Oil and water) or buying a spritz. I personally swear by Oyin's Frank Juice, but she may want something she can buy locally.

At this point, I turn it over to you folks. Any product recommendations for my sister or tips you want to share for winter hair care? She'll be watching this post!
