    Expert Answer
    Sure! As a board certified dermatologist, there are a few natural remedies that can work, such as apple cider vinegar and lemon juice, which can help restore the pH levels of the scalp and hair follicles, just be sure to dilute them. If you’re experiencing seborrheic dermatitis or dandruff, you may be better off with a sulfate free shampoo like head and shoulders to rebalance your pH.

    Why then do we rinse hair with just water which has a pH of 7 when hair is closer to 5.5? Would it be good to use a slightly acidic final rinse?

    Soft water is better for your hair than hard water, but some people do find that their hair looks limp after they switch to soft water. Try using a volumizing shampoo and avoid heavy conditioners, and see if that helps!
  • Question
    How do I restore my natural ash blond color after a perm that turned my hair yellow?
    Community Answer
    Try Bantu Yellow Out conditioner by Soft Sheen Carson. It will take out the yellow cast, and works on other colors too. You can get this at beauty supply shops or online. Or you can also try squeezing the lemon into your own conditioner. Shake well, then apply. Leave on for at least 10 minutes with a plastic bag covering it. If the cast is still there after a rinse, just apply more.

    What would be the pH value of a quality hair conditioner?

    Should be between 4 to 7, because our average hair pH level is 4.5 to 5.5. The conditioner needs a slightly-acidic level to close the cuticle.

    Ask for a hair product in a professional salon for re-growth and that makes the roots strong. And use a PH balance shampoo from professional brand. If the loss is really severe, see your doctor.
  • Question
    Why is pH important in shampoo selection?
    Community Answer
    It is important to maintain the correct pH in your scalp and hair so it does not become dry, brittle or frizzy. Your hair generally has a pH of 4.5 to 5.5, which is acidic. Usually, more acidic hair will have closed hair cuticles, while more basic hair will have more open hair cuticles. For straight hair, use a shampoo that is neutral or slightly acidic (6 - 7 in pH). Curly hair is more basic, so to reduce frizz, use shampoos that are more acidic (4.5 - 6 in pH). However, shampoos that are too acidic (0 - 4 in pH) may cause your hair to become brittle and dry, as it reduces moisture absorption.
  • Question
    How do I find the pH level of a shampoo?
    Community Answer
    Use litmus paper - specifically the ones that come in a bottle that shows you the PH range you should compare the test strip to. Most shampoos will not tell you outright what the pH level is.
  • Question
    My scalp itches like crazy sometimes. I have dandruff and my scalp gets oily every 2-3 days. At the same time I have dry hair. Recently my hair loss has increased drastically. What can I do?
    Community Answer
    If you have washed your hair more than or about twice a week for a long period of time, or even your life, then it is possible your shampoo is too intense on your scalp. Once a week of washing your hair with about two dime-size amounts of shampoo should work for most people and only wash your scalp gently. Try washing your hair less because your shampoo likely strips your scalp of its natural oils, making it produce even more oils to compensate for the loss of oils. Remember to properly condition your hair and/or oil your hair if needed skipping out on hydrating your scalp could also make it very dry, try hair masks, and gentler/intensive conditioners/shampoos.
  • Question
    Can I know the pH of the hair protein that I applied on my? What is the effect on hair if its pH is 1 or 1.5?
    Community Answer
    The average pH of hair is between 4.5 and 5.0. If your hair's pH is significantly higher than 5.0, it will provoke your hair cuticle to open, and if your hair's pH is significantly lower than 4, the cuticle will close. When hair is not between the ideal pH range, it is less ideal and could even damage your hair.
