    - Studies have shown when applied trans-dermally, this powerful ingredient increases blood flow to the scalp, providing more nutrients for your hair to thrive. This helps extend the life cycle of hair follicles and encourage healthy hair growth.

     Saw Palmetto

    - Clinical studies have shown that this powerful plant based ingredient reduces inflammation and helps block dihydro-testosterone (DHT) in the scalpInflammation and DHT are considered a major cause for both male and female hair loss. 

     Castor oil

     - When massaged into the scalp, these compounds get straight to work. Research shows caster oil may stimulate blood circulation, nourish the scalp and provide nutrients to the hair roots naturally.


     – Designed to fight grey hairs and promote hair health. As we age the hair follicles produce less melanin, the pigment responsible for hair colour. This bio-mimetic peptide stimulates melanin synthesis increasing the number of pigmented cells in the hair bulb helping to maintain natural hair colour and health. This ingredient can be used as a preventive or for reducing grey hairs.

    Hi I am enjoying this product the smell is amazing there has been a slight improvement in the thickness of my hair I will continue to use for continued improvement.

    Gentle shampoo that reduces hair loss

    This shampoo is so far the most gentle yet effective shampoo I have tried. I seem to loose less hair. I am anxious to switch back to my old shampoo. Works for me.

    Healthy Hair

    I have been using this hair shampoo to help hair regrow for the last two years. Having itchy scalp and loss of hair, I tried everything even saw a skin specialist, nothing helped. Since I have used the shampoo my hair started to grow back and it eased the itching considerably. The shampoo certainly has helped and leaves my hair soft and shiny, I don’t even need to use conditioner.

    Hair is Back

    I can see new hair growth on my husband after a month of use. It has been 4 months now and I can see more hair growth. I am using as well and I like the look and feel of my hair. Will order again.

    Review on Hair Hack Shampoo Conditioner twin pack

    I have been diagnosed with FFA (Frontal Fibrosing Alopecia) and I find that this product gives my head a cooling sensation when I use it which has been making the condition easier to deal with. Thank-you for developing this product.

    I’ve been using the shampoo and conditioner for about 3 months in combination with hair growth supplements and are seeing results. I like how natural this product is compared with other hair treatments.
