So y'all just gonna let me be bald?
I have an answer. It is probably not what you want to hear, and its long winded. You can enjoy all of the fun hair growth tools, products and techniques after you figure out what is causing your hair loss. So my first suggestion is to consult your doctor or dermatologist to determine what is officially causing the baldness and the appropriate ways to treat it. If the bald spot is not caused by SB, but you are treating it as such, then you could be spinning your wheels for nothing. Treatments for seb derm will not resolve bald patches caused by anemia.
Additionally, another reason to stop self medicating is because everything doesn't need a hair growth stimulant in order for the hair to grow back. Hair loss due to chemo often needs absolutely nothing to regrow once the treatments have stopped. Hair loss due to contact dermatitis only needs you to stop being exposed to the irritant in order for hair to grow back. Even hair loss due to scalp infections like ring worms only need you to clear up the infection in order to have the hair grow back. So it is very important to know why you are having a bald spot.
Real life experience (read if you want)
I'm going to give you an example of what has happened to my youngest brother. He suffers from what looks like male pattern baldness much like my dad. He has been treating it on his own with topical minoxidil and dermarolling. It actually was working pretty well until it wasn't. He was frantically looking for not so invasive ways of controlling the hair loss. He also started having pain in his lower back and didn't feel too well. He thought he pulled a muscle while weight lifting. During this time, he didn't think his other health issues that were arising had anything to do with the increased hair loss.
So he finally goes to the doctor. It turned out he was suffering from a vitamin D deficiency. Not only did they prescribe vitamin d supplements, but they prescribed that he goes out in to the sun daily. He had started working from home and those few months of being constantly indoors during daylight hours were affecting him. So with the vitamin d pills and daily walks outside, his hair started growing back instantly.
Almost a little over a year later, my brother has started having back pains again. He also is starting to have hair loss again. He also switched jobs and now works from home again. He even stopped taking his vitamin d and is basically living off of a keto diet. He assured the doctor that he is getting sunlight, but going out with friends once a week right before sunset is not the same thing. The doctor then thought he might have a bulging disk. So they sent him to an orthopedic doctor. That doctor says it might be a spinal growth development disorder. That doctor sends him to a physical therapist. Then he goes to a physical therapist who doesn't see any real issues with his spine and thinks he "might" just be having tight muscles. Yes, I'm being facetious. I keep telling him to treat his rickets by stopping his vampirism and getting some sunlight. Mind, you he is not doing that very well.
I'm going to bring it back to his hair loss. He never went to a dermatologist to treat his hair loss in the first place and still hasn't. He was afraid to be prescribed something like propecia, yet he hasn't done anything to block the dht. Even now, he prefers to do his own thing for his hair loss. What if his initial hair loss wasn't even caused by androgenetic alopecia? Luckily, the minoxidil has for the most part been working. What if her never found out that he had a vitamin d deficiency the first time? He would still be throwing everything at the increasing bald spots, but having none of it work. All of his current efforts may be in vain because he is not treating the cause. He is only trying to stimulate hair regrowth.
Secondly, It sounds like your skin barrier is still damaged. When damaged, even using products that are deemed gentle can feel harsh. You may have to take it slow with you hair regrowth efforts. More irritation to that area will not work in your favor. This is the sad reality of sensitive and sensitized skin...be gentle and slow. Work on stopping irritation first before treating the bald spot. Just because the flakes are gone doesn’t mean that area is fully healed.
Third, based on the assumption that the bald spot is caused by seb derm, I would say refresh yourself on what supposedly causes seb derm and how to properly treat it. Remember that Seborrhoeic Dermatitis is often thought to be caused by an overgrowth of Malassezia yeast. When out of balance, this yeast triggers inflammation of the skin that causes scaled skin and red patches. So, make sure you are not feeding the yeast with oils that it enjoys eating. It thrives off of an oily scalp. Also, it can be triggered during hormonal changes, weather changes, stress level changes and even with changes to things like using a new detergent. Those changes are usually still centered around oil or oil production. So be mindful when using things like topical oils as a hair regrowth treatment. For instance, it may not be the active that causes the problem, but instead something like the carrier oil that triggers the issue.
Fourth, refrain from habits like picking and scratching irritated skin because that can cause damage to hair follicles.
Fifth, getting the seb derm condition under control will greatly increase your chances of hair regrowth. Increase you frequency of washing your scalp. Also, that prescribed shampoo might be needed more often. If its not working, let your doctor know. You might need to switch treatments or even the treatment plan all together..
Hopefully, it turns out that your bald spot is easily treatable and even better if curable. Once you get a handle on the cause, you may find that your hair regrows effortlessly. To speed up the process, you should try what
