While natural shampoo bars may be gentle and free from harsh chemicals, it's generally advised to avoid using any soap or shampoo on babies below 6 months of age. A newborn's skin is extremely delicate and sensitive during this early stage of life. Even the safest products, including natural alternatives, may be too harsh for their delicate skin.
For babies under 6 months, it's recommended to stick to simple and gentle cleansing methods. You can opt for natural alternatives like using a mixture of milk, curd (yogurt), or besan (gram flour) for mild cleansing. These ingredients are known for their gentle and moisturizing properties, which can be suitable for a baby's sensitive skin.
As your baby grows older and their skin matures, you can gradually introduce mild and baby-friendly products.
