The white hair of Geralt of Rivia, the titular character of the Witcher series, is a defining characteristic of his appearance. However, the reason for his white hair is not explicitly stated within the series. Instead, it is left to speculation and interpretation by fans and readers.

One possible explanation for Geralt’s white hair is that it is a side effect of the mutations he underwent to become a witcher. Witchers are warriors trained from a young age to hunt and kill monsters using their enhanced physical abilities and magical powers. As part of their training, witchers undergo a series of grueling trials and experiments known as the “Trial of the Grasses,” which imbue them with their abilities but also cause severe physical changes. It is possible that the Trial of the Grasses resulted in Geralt’s white hair as a side effect of the mutagens used during the process.

Another possible explanation for Geralt’s white hair is that it is a genetic trait of the witcher bloodline. It is mentioned in the series that the first witchers were created by the sorcerer, Lara Dorren, using her own bloodline as a base. It is possible that the white hair trait was present in Lara Dorren’s bloodline and was passed down to Geralt through his witcher heritage.

Alternatively, Geralt’s white hair may be a result of the use of magic in his everyday life. Witchers are highly skilled in the use of magic, and Geralt is no exception. He is known to use powerful spells and potions on a regular basis, and it is possible that the constant exposure to magic has had an effect on his hair color.

In conclusion, the exact reason for Geralt’s white hair is not known for certain and is open to interpretation. It may be a side effect of the mutations he underwent to become a witcher, a genetic trait of the witcher bloodline, or a result of his constant use of magic. Regardless of the reason, Geralt’s white hair is a distinctive feature that sets him apart from other characters in the series.
