Vaseline, also known as petroleum jelly, has a long history of usage in skin and hair care. While it can provide benefits to hair, it can also cause some issues such as hair greasiness, tangling, and hair loss if not used properly. Here are some details about using Vaseline on hair:

Positive effects:

• Protects hair against breakage and dryness
• Can be used as a styling gel for frizzy hair
• Can be used to combat flakiness by massaging a small amount into the scalp before rinsing with shampoo
• Can help seal split ends and moisturize hair

Negative effects:

• Can cause hair greasiness, tangling, and hair loss if not used properly

Ingredients or materials:

• Vaseline is made of petrolatum, which is a great lube and can be used to prevent skin chafing
• Vaseline is incredibly difficult to get out of hair, especially if too much is used

Its important to note that there is no scientific evidence to support the popular claim that Vaseline makes hair grow faster. However, it can be a good addition to a hair care routine for other benefits. Vaseline is non-irritating and hypoallergenic, and Vaseline Jelly Original is even recommended by dermatologists and recognized by the National Eczema Association as appropriate for use on sensitive skin.
