By looking at the history of Islam, and how close Imam Ali (a.s.) was to the holy Prophet (s.a.w.), and their frequent travelling, along with the victory of conquering Meccah al-Mukarramah, this leaves no doubt that Imam Ali (a.s.) performed Hajj, and visited the holy Ka'bah, which was his birthplace.
We can see the many instances of how Imam Ali (a.s.) describes Hajj, in Nahj al-Balaghah, and in other sources as well.
Furthermore, we know about the authentic mutawatir hadith of Hajjatul-Wida', where on their way back from the last Hajj, our beloved Prophet (s.a.w.) announced the succession and wilayah of Imam Ali (a.s.).
The main reason is that it was not mandated by the Prophet; in fact, he prayed with his wife and daughter there.
Also, (a) because to do tawaf you have to go all the way around the Ka'bah, and that is difficult to do with segregation, similarly it might be challenging to arrange gender segregation for sa'i between Safa and Marwah, and (b) perhaps it could cause hardship for people travelling together.
While it is true that there are some people with sick minds who misuse the arrangement there, by and large, I think most Muslims behave themselves properly there and respect the sanctity of the place, and the rules of ihraam (forbidding certain things between genders) also provide extra incentive to behave correctly, even if they may run into each other by accident.
That being said, wearing an extra outer garment can help provide more personal space without inconveniencing others.
If you are a man and your Hajj is the first Hajj, you must shave your head on the day of Eidul Adhha as one of the obligatory acts of Haj according to most of the scholars.
If your Hajj is not the first Hajj, it will be highly recommended to shave your head.
