Here is my follow up and the start of my quasi-scientific experiment. To be clear, I will try to find my scalp's thickness in different zones assuming that a drop of blood indicates the same depth. I will then map different DR sizes to different zones of my scalp. I will try to keep the same pressure across my scalp while doing this. Some may argue that a drop of blood is not an indication of collagen production. I can't argue with this right now and that is not the goal of the experiment, yet! That can be a follow up discussion.
I also figured that to do the experiment properly, I cannot treat on the same day different DR sizes as each application will skew the next. The treatments must be performed sufficiently apart so they are independent of each other. So, I will use my weekly treatment which I perform for the purpose of collagen production. I do treat everyday or every other day for absorption also but I assume that this will not skew the results as the absorption treatment will be performed consistently.
To conduct the experiment, I will always use DRs with 540 needles, meaning the same width DR. The treatment will be across the complete NW7 area and will consist of the suggested application of 4-5 rolls in the 4 known axes. I plan to use any size available to achieve the goal from 0.25 to larger. I made a mistake ordering another 0.25 (which I already have) instead of a 1.5mm but will get it this week. I don't have a 0.75 right now but may need to order it if the 0.5 and 1.00 are too far apart. I am starting with a 1.00 mm on my complete scalp and will increase or decrease the size on the next treatment (1 week later) to achieve uniform visual blood drops, same density and same pattern. I mention pattern because in certain zones I get streaks of drops (can be seen in pics). The adjustments will be as follows:
- The drops of blood need to be visual but the smallest possible. Comparing all the drops on my scalp, the smallest sized drop will be the goal. If certain zones have larger drops then a decrease in size is needed as long as drops can still be seen.
- Density needs to be the maximum possible non-touching drops per inch. I will not try micro adjust for zones which are smaller than 1 inch as it would be too tedious. If the drops are touching then a smaller size is warranted. If they are too far apart and other drops can fit in between, an increase in size should be used.
- If streaks are perceived, a decrease in size is probably warranted.
- I will ignore differences in skin redness in this experiment.
Finally, my first pictures with a DR of 1.00 mm. You can see in the frontal picture the redness which indicates where I applied the DR. Certain zones do not have any drops while other zones have streaks (red ovals) which in my current opinion is too much. The crown picture shows some drops also but they are very disparate and the redness cannot be seen even though I applied the same treatment. The DR did flake my scalp but I wanted to take the picture right away so here we are. I will use those pictures the next time to guide me with different sizes and as you can tell, I need a larger size for most zones but will try the 0.5 where I have streaks. I like the density in certain parts of the zones I squared in green as you can see the blood drops but they are very small. I will also change my regimen to shave a day before and DR the next day (I do the oppose now) so that it is easier to see the drops clearly.
