There are remedies galore for making hair grow thicker...one old time remedy was rinsing your hair with vinegar, another use castor oil on your hair, and taking biotin was said to make hair grow faster and thicker. Harper's Bazaar says massage your scalp, use lots of conditioner, skin/hair/nail vitamins, and avoid stress. Other suggestions include brush less, use less heat, and horse shampoo - yes, it's sold at Kmart or Walmart. There are probably as many remedies to make your hair thicker as there are hairs on your head. Do they work? I don't know but there's lots of remedies out there.
