There are a few other active ingredients you could try for dandruff (seborrheic dermatitis), if that's what's causing your problem. Keep in mind that it might actually be a different problem, such as eczema or scalp psoriasis. From a quick internet search, the active ingredient in "Dettol Anti-bacterial Soap" is cholroxylenol, is that correct? If so, here ...
There are two main things to consider here:
What kind of hairloss is there?
What is in the product that is applied to the hair?
concerning 1: All humans loose their hair, constantly. That is part of the life cycle of hair und usually goes quite unnoticed when the hair is short and is progressively more obvious when the hair was allowed to grow longer.
One big problem here is that it's difficult to do double blind studies. One is then forced to use more theoretical arguments, but because medical science is not a hard science like physics, such arguments are not very reliable. The best we can then do is argue from biological plausibility, in this case we should take serious the fact that Homo Sapiens ...
I can offer only partial answer to your question, and that is on how this shampoo works.
From The Electronic Medicines Compendium:
Mechanism of action
Coal tars suppress DNA synthesis in hyperplastic skin inhibiting mitotic activity protein synthesis and cell reproduction.
Coal tar decreases epidermal proliferation and dermal infiltration and thus ...
Every single website that suggests onion juice is good for hair regrowth doesn't have credible sources. I went through a lot and all of them are full of mumbo jumbo and charlatans.
However, this onion madness seems to have some.. I repeat some... scientific basis and maybe that's where it all started.
There is an actual research paper on the matter:
The NHS recommends not to use any of the following treatment options:
products containing permethrin
head lice "repellents"
electric head lice combs
tree and plant oil treatments, such as tea tree oil, eucalyptus oil, and lavender oil
The very basic option:
Wet combing involves removing head lice with a special fine-toothed
There are more possible causes, other than generics, as described here:
Stress can also affect your hair. A 2013 study found a connection between stress and a depletion of stem cells in the hair follicles of mice. So if you’ve noticed a rise in your number of white strands, stress might be the culprit.
An autoimmune ...
Growing a beard is mostly due to genetics and your sensitivity to testosterone levels:
When people have no facial hair, they tend to think it’s because of the fact that they have low testosterone. That’s not the case, it’s actually based on how sensitive your body is to testosterone. In other words, if you are highly sensitive to it, you’re going to have a ...
Malassezia overgrowth is thought be the cause of most cases of dandruff (1) and rotating treatments avoids the development of resistance. However, some have argued that overgrowth of Malassezia is a result rather than a cause of dandruff (2).

There have been a couple of studies, including the one you cite, that link finasteride with persistent erectile dysfunction. (Bear in mind that the rates of PED reported in these studies are actually quite low, and it is possible that they are due to other factors.)
There is also a meta-data analysis of the clinical trials for finasteride claiming that ...
1) How likely is intracranial thrombophlebitis after nasal hair removal?
Cavernous sinus thrombosis (Stat Pearls, 2019) after nasal hair removal (or from any cause) seems to be rare but possible:
...annual incidence of cavernous sinus thrombosis might be
approximately 0.2 to 1.6 per 100,000 per year.
Cavernous sinus thrombosis (CST) is a rare, ...
Currently, there seems to be no convincing evidence to say that alternating between shampoos prolongs their effectiveness in treating dandruff.
1) According to the Scientific Committee on Cosmetic Products and Non-food Products Intended for Consumers by European Commission, 2012:
There is at present no scientific evidence of development of
The personal set-point of thyroid homeostasis may differ between individuals [1, 2]. Multiple studies showed that the intra-individual variation of both TSH and peripheral thyroid hormones is smaller than the inter-individual variation [3, 4]. Therefore, for individuals the range of optimality is smaller than the width of the corresponding reference range (...
No, long hair has a appearance of falling out. But everyone's hair is constantly falling out. Hair generally falls out at a rate of 50 to 100 strands of hair a day. And regrowth of the hair generally matches that rate.
Longer hair is more noticeable than short. And our hairs are more ...
Yes, there is a name for this. It is a paresthesia.
In layman's terms, a paresthesia is defined as:
A skin sensation, such as burning, prickling, itching, or tingling, with no apparent physical cause. (American Heritage Dictionary of the English Language)
If the sensation were relieved as long as the hair wasn't touching the skin in an unusual way, it ...
The study did not investigate the causes of, or possible treatments of, grey hair. However, the research focused on vitiligo, specifically looking at segmental vitiligo (NHS, 2013).
The NHS went further by saying that:
Though the blame for the poor reporting of the study can be put at the door of the press office of the FASEB, which issued a press ...
I haven't read the article, only the abstract, but what it's saying is that, for people with grey or white hair, darkening of hair color is an indication that anti–PD-1/anti–PD-L1 treatment for lung cancer is working. This is almost entirely unrelated to reversing age-related hair depigmentation.
(As a side note, I consider the Daily Mail to be comparable ...
These are extracts and links:
Other proposed treatments include saw palmetto extract (Serenoa Repens); prostaglandin analogs like latanoprost and bimatoprost, which may be cost prohibitive
Serenoa repens(commonly called Saw Palmetto) extracts promote hair regeneration and repair of hair loss mouse models by ...
