2) Soft and shiny
3) Thick and voluminous
4) Oily and greasy

Answer 1

Shampooing often with a high pH shampoo can cause hair to become dry and brittle. Shampoos with slight acidity and conditioning agents are more beneficial for maintaining hair health.

Step-by-step explanation:

Shampooing often with shampoo that has a high pH or high alkalinity will cause hair to become dry and brittle. The natural pH level of hair and scalp is somewhat acidic, ideally remaining around 4.5 to 5.5. Using a high pH shampoo can strip away the natural oils from the hair and scalp, leading to a lack of moisture which results in dryness and brittleness. Shampoos should ideally have a slight acidity (pH less than 7) to maintain hair integrity and prevent damage. It's also essential to consider shampoos containing conditioning agents like silicone for added benefits and to repair damage already done to hair. Furthermore, desirable qualities of shampoos include pleasing foam, ease of rinsing, minimal skin and eye irritation, and good biodegradability.
