I still use oral and topical growth aids. I have just began journalizing what I use so that I can monitor growth/improvement if any. I take an arsenal of supplements, many for their potential to accelerate hair growth. Additionally, I apply topical growth aids on my hair. The disadvantage to this approach is not knowing which (if any) of the growth aids would be responsible for increased hair growth (if any).
Another consideration is that the various supplements may deliver other benefits to my body and health. For example more energy, my skin is so soft, supple and clear - even I am amazed. The multi-vitamin, pre-natal, biotin, or vitamin C could be responsible for my skin, or maybe all combined. Not to mention benefits which I may not even realize (fighting high blood pressure, fungus, bacteria, etc. )
Another school of thought is: Could one supplement be contraindicating (cancelling) one or more of the other supplements or their ingredients?
I plan to take a more focused approach to taking supplements and using growth aids in the months to come. I've already reduced my topical growth aid to one aid. I will use this aid for 6 months and monitor progress. If I don't see any, I will move to the next. As far as oral growth aids the only supplement I will consider eliminating is the pre-natal vitamin. It has overlap with my multi-vitamin. But if it delivers a mineral, vitamin or amino acid that I'm not getting from something else. It stays.
The end goal is to have a well-thought out regimen (oral and topical) that will not vary from month to month.
