HOW CAN SHAMPOO PREVENT HAIR LOSS?

Shampoo is in contact with the the scalp for a very limited amount of time limiting the potential effects in hair follicle growth.  Shampoo can be more effective when there is a scalp condition such as dandruff or psoriasis that is exacerbating a hair loss problem.  Hair loss due to androgen and estrogen hormonal imbalances may not be very responsive to treatment with hair loss shampoos and conditions such as alopecia areata or androgenic alopecia are very unlikely to respond to treatment with a hair loss shampoo.  Milder types of hair loss due to excess shedding can be treated with some clinical shampoos to increase the number of hair follicles in growing phase and reduce shedding to increase overall volume. In combination with other hair loss therapies such as minoxidil and phytoestrogen therapy, hair loss shampoos can help reduce hair loss and encourage hair regrowth.

5 TOP SHAMPOO INGREDIENTS FOR HAIR GROWTH

Blood is made up of vital elements for hair growth such as hormones, iron, amino acids, glucose and oxygen.  The amount of of blood that reaches their follicle is one determinant of how fast or how thick hair will grow.

  1. Zinc pyrithione – A 1% concentration of zinc pyrithione in shampoo decreased hair shedding by 10.1% and increased hair follicles remaining in anagen by 6.8% when used 2- 3 times per week for 6 months [1].
  2. Ketoconazole – A 1% concentration of ketoconazole in shampoo decreased hair shedding by 4.9% and increased hair follicles remaining in anagen by 6.8% when used 2- 3 times per week for 6 months [1].
  3. Caffeine – Caffeine has been shown to be an effective follicle stimulator at very low concentrations.  Clinical trials have shown caffeine can effectively penetrate the epidermis and stimulate the hair follicle to remain in growing phase for a longer period of time.
  4. Safflower (Carthamus tinctorius L) –  Carthamus tinctorius L extracted with ethanol has been shown to be an effective DHT inhibitor and showed significant growth promoting activity.
  5. Piroctone olamine – A 1% concentration of piroctone olamine in shampoo decreased hair shedding by 16.5% and increased hair follicles remaining in anagen by 7.9% when used 2- 3 times per week for 6 months [1].
