I want to help you by sharing how I achieved armpit length hair using my current hair regimen. It’s a pretty simple yet effective routine that works great for me. You can review my regimen and adjust it so that it fits your needs.
My ultimate goal is to reach Bra Strap Length (BSL). From that point on I will trim my hair so that it stays at BSL as any longer is personally too much for me.
My Current Regimen
My go to styles: I love pony tails and twist outs. As of now I mostly wear low manipulation styles. I do wear protective hairstyles, but I do it in cycles so to speak. For instance I may wear box braids for two months or I will wear something like my natural hair wig that I made for a month. So I pretty much give my hair balance, I will go through long periods of protective styling to make it easier on my busy schedule and for length retention. Then once I am done, I let my hair breathe by wearing styles with my hair out that do not require daily styling, combing, or manipulation of any sort.
Detangling: I like to wait a least a week (sometimes longer) before detangling my hair and I typically only comb it if I am getting ready to wash my hair. My hair always has some sort of dampness from a product and or water before I detangle.
Moisturizing: Since my hair is now worn out more frequently, I moisturize it more often. On average I would say I moisturize just about everyday by either spritzing (not saturating) my hair with water or using my favorite products which are: Shea Moisture Curling Souffle, Miss Jessie’s Baby Buttercreme, or Shea Moisture Raw Shea Deep Conditioning Masque. To seal in the moisture I love to use Vitamin E Oil or Jojoba Oil. I also make sure the ends of my hair get a lot of love, as the ends of hair need the most attention.
Wash/Conditioning: In colder weather I wash my hair every 2 -3 weeks and in warmer climates I wash my hair every week. Every time I wash I aim to deep condition with Elasta Deep Conditioner for 15-30 minutes under a hooded dryer.
Protein Treatments: Every so often, I use Apoghee Protein treatments. This is pretty strong stuff! You only need to use this every 6 weeks.
Heat: When I do use direct heat, I use the tension method for blow drying so my hair is not damaged from manipulation. In colder temperatures on average I blowdry once per month. In summer weather I do not use heat at all, because that would be pointless! Plus, I like to try to keep my heat usage down to a bare minimum.
Search and Destroy: Every time I see damaged ends or splits, I cut them off with my hair cutting scissors. I do trims on my hair on a as needed basis.
Vitamins: I currently take Biotin (which is known for improving hair, nails, and your metabolism) and Fish Oil (which is good for blood pressure, heart disease, and a number of other health concerns).
Nightime: I keep my hair wrapped at night with a silk or satin scarf. To prevent my hair from getting matted or tangled I pineapple my hair or put my hair into large twists.
I make up my own rules! I do what works for me. You can always learn from others how to care for your hair, but always take this information and tweak it so that it works for you and your hair.
In short, I would have to say black hair growth is a matter of Good Care + Time. I will handle teaching you the good care bit and you will have to be patient in understanding that growth takes time.
In my post How Long Does it Take to Grow Natural Hair Long, I discussed the average time it takes to achieve long natural hair. Many of the kinky hair icons in the natural hair community have spent a minimum of 3 to 4 years before achieving long hair. Of course there are exceptions to the rule, as some women may have faster growth rates and their strands may be able to withstand more strain before reaching its breaking point. But I think you get it! You just have to have some patience.
