How should Samuel tint his beard if he dislikes its effect after tinting his scalp hair?

The best approach for Samuel, considering that he is dissatisfied with the effect of tinting his scalp hair, would be to leave his beard natural. Keeping the beard in its natural state can create a more harmonious look, especially if he is unhappy with the result of the hair tinting. This allows for a softer transition and maintains individuality without introducing additional colors or styles that may not suit him. Tinting the beard dark, short, or red could exacerbate the issue of dissatisfaction by potentially clashing with the scalp hair color or giving an uneven appearance overall, leading to a look that is less natural and may feel too forced or striking against his desired aesthetic.
