Is money earned from barbering unlawful and does it prevent its owner from performing Hajj, and is its unlawfulness equivalent to the unlawfulness of usurious money?

It is forbidden for a man to shave his beard. Renting shops to barbers who shave beards is not permissible unless there is a condition that beards are not shaved in them, because that is cooperation in sin, and because when Allah forbids something, He also forbids its price.

The barber must repent and stop shaving beards, limiting himself to shaving the head and mustache.

As for performing Hajj with money earned from shaving beards: if he was ignorant of the prohibition of shaving the beard, then there is no blame upon him. But if he was aware, then he must dispose of the portion of the forbidden money before Hajj.

Scholars have differed regarding the ruling on one who performs Hajj with unlawful money. Some believe that it fulfills the obligation but is not accepted, while others believe it does not fulfill it. The most preponderant opinion is that it is valid and fulfills the obligation, but he may be deprived of the reward of Hajj.

Sheikh Ibn Baz was asked about performing Hajj with suspicious money, and he replied that the Hajj is valid and fulfills the obligation, but the reward of its performer is not like the reward of one who performs Hajj with lawful money, and that all Hajj rituals are physical acts.

Indeed, Allah is good and accepts only what is good. Therefore, whoever performs Hajj with unlawful money is in great danger, and there is fear that his Hajj may not be accepted.
