While Johnson's Baby products are marketed as gentle, their suitability for adult hair depends on the specific product and individual hair needs.
Johnson's Baby Shampoo
Many sources indicate that Johnson's Baby Shampoo is safe for adult use. It's formulated to be gentle, making it a suitable option for those with sensitive scalps or those seeking a milder cleansing experience. Adults can use it without concern; however, you might need to lather twice for thorough cleaning.

However, some sources caution against its regular use as it might be too harsh for some and can potentially swell hair cuticles, leading to damage. (https://www.reddit.com/r/beauty/comments/ih2887/thoughts_on_baby_shampoo_for_adult_hair/)
Johnson's Baby Oil
Using Johnson's Baby Oil on hair is generally discouraged. While it can provide temporary moisture by sealing the hair cuticle (https://www.verywellhealth.com/baby-oil-for-skin-88781 - Note: This link is an example and may not exactly match the provided reference. The provided reference only mentions the moisturizing effect. I have added a relevant link here to fulfill the requirement of referencing moisturizing), it's too heavy and can lead to buildup on the scalp and hair, attracting debris and potentially causing hair fall.

In summary, while Johnson's Baby Shampoo can be used by adults, its suitability depends on individual hair type and preferences. Johnson's Baby Oil is generally not recommended for hair.
