Keratin treatments are commonly used in barbershops for hair straightening due to their effectiveness in smoothing and softening hair. These treatments involve the application of a keratin-based formula, which can help in reducing frizz and making hair more manageable. The process generally includes applying the treatment and then using heat to seal it into the hair cuticle, resulting in sleek, straight hair that can last for several months.

Unlike hair gels, which primarily offer hold and styling without changing the structure of the hair, keratin treatments chemically alter the hair's texture, allowing for a more permanent straightening effect. Hair mousse provides volume and styling support but does not have the same hair-smoothing properties. Leave-in conditioners are excellent for moisture and can help in taming frizz but do not offer the same level of straightening as keratin treatments. Therefore, in the context of barbershops focusing on straightening hair, keratin treatment stands out as the most fitting choice.
