Possible good news for us that haven't gone to OCS yet, those in the fleet already with nice commands, and African American women!! Lock styles are approved for all wear, and ponytails/braids may be approved for PT!! The new female standards for hair are also on the OTC Newport official website under FAQs regarding approved styles. So fingers crossed ??
Here's the NAVADMIN for it:
https://www.public.navy.mil/bupers-npc/reference/messages/Documents/NAVADMINS/NAV2018/NAV18163.txt
"3. Female Hair Grooming Standards. Effective immediately, the female hair grooming standards are expanded. Wearing of approved hairstyles is
authorized provided doing so does not prohibit the proper wear of safety and damage control equipment, facilitates uniform head gear being worn squarely on the head, and does not present a safety hazard to the Sailor as determined by the unit commanding officer"
"a. Braids and Ponytails. Current policy permits commanding officers to relax hair grooming standards during command/unit physical training to include allowing free hanging ponytails. Policy is now expanded to authorize wear of a single braid, French braid, or a single ponytail in Service, Working, and PT uniforms. The initial accessory for the ponytail will not be visible when facing forward. Authorized accessory devices must be consistent with the color of the hair."
"c. Lock Hairstyle. For the purpose of Navy Uniform Regulations and grooming standards a Lock Hairstyle (Locks) consists of one section of hair
that twists from or near the root to the end of the hair and creates a uniform ringlet or cord-like appearance. Locks may be worn in short, medium,
and long hair lengths in the following manner..."
And lastly, less significant and for later:
"d. Relaxed Hair Requirement with Dinner Dress Uniforms. Female Sailors are authorized to wear their hair below the lower edge of the collar of the blouse, jacket, or coat of the Dinner Dress Uniform being worn. All other hair grooming requirements will be observed."
Those are the highlights. I recommend reading the entire thing. It addresses the new PT uniform, the Eisenhower jacket, and the ID Badges manners of wear for females (it changed sides), as well as about new, apparently more comfortable boots.
