Is baldness one of the defects that a suitor is required to disclose?
I have thinning hair on the front of my head, i.e., all the hair on the front of my head is thinning and my scalp is visible; the same is true of a small part of the back of my head. Is it possible that I could do something Islamically prescribed or permissible, such as surgery and the like, to change its appearance, and what is your opinion on applying kohl to my head to conceal the baldness?
Would I have been deceiving my boss or manager at work, and would there be anything dubious about my salary, or am I taking my salary for my effort and my work, and does it have nothing to do with my hair?
Secondly: if I get married, and I do not tell my fiancée the truth about my hair or, for example, if I tell her but she has not seen my head, would my marriage be regarded as invalid?
Praise be to Allah.
Firstly:
In the answer to question no. 194116 we stated that there is nothing wrong with applying kohl to conceal baldness, and that is not regarded as changing the creation of Allah, may He be exalted; rather it comes under the heading of permissible adornments.
You do not have to tell your boss about it, because it does not have any impact on your work; hence it does not have any impact on your salary either.
Secondly:
The basic principle is that it is not permissible for the suitor to conceal any defects that may have a negative impact on married life in the sense that the wife would be put off by them, or they would prevent intimacy between them, or would make him unable to fulfill his wife's rights.
Based on that:
If the baldness is minimal, or it is something common and ordinary, then you do not have to disclose it.
But if the baldness is complete and may be off-putting, or it would affect the woman's decision to marry, then in this case it is not permissible to conceal it, because that is a kind of deception.
There is nothing wrong with you having hair transplant surgery; in sha Allah that will be a means of correcting the defect.

And Allah knows best.
