Hair Growth Shampoo Twin Pack

  • Make a Selection



This plant based shampoo features high grade ingredients to produce thicker, healthier hair, Plus gently cleanses the scalp of DHT build up. Unrivalled results when coupled with HairHack™️ Conditioner.

This zingy, peppermint-scented Shampoo is power-packed with 10 high-grade active ingredients. If you’re not using Shampoo and Conditioners that help block the formation of DHT and are packed with high-grade nutrients for your hair and scalp, You’re missing a big opportunity for thicker, fuller, stronger hair.



Main Active Ingredients:



-A unique blend of peptides and red clover extract. Capixyl™️ has a direct action on 5-a-reductase which modulates dihydro-testosterone (DHT) to help prevent hair miniaturisation. It improves ECM Proteins in the follicle bed  producing thicker, healthier hair.



-Studies have shown when applied trans-dermally, this powerful ingredient can help extend the life cycle of hair follicles and encourage healthy hair.


Saw Palmetto

-Clinical studies have shown that saw palmetto may block an enzyme, 5-alpha-reductase,which facilitates the change of testosterone into DHT. DHT is considered a major cause for both male and female pattern baldness.


Castor oil

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



 –Designed to fight grey hairs! As we age the hair follicles produce less melanin, the pigment responsible for hair colour. A bio-mimetic peptide Melitane™️ stimulates melanin synthesis thus decreasing the number of white and low pigmented cells and increases the number of pigmented cells in the hair bulbs.

      Hair Loss

      I originally ordered HairHack to see if it would stop my hair falling out every time I brushed it. I've only been using the shampoo and conditioner a short time but I have noticed there is hardly any hair in the brush and it's looking much healthier and shiny. I have great hopes it will thicken in the future.

      Happy customer!

      I am happy with my purchase. Have tried other shampoos that have promised thicker, fuller hair that have failed to deliver on their promise. I am seeing less hair loss and my hair is looking shiny and healthy.

      Product that delivers!!

      I've been using hairhack for more than a month now, and never been happier with the results, my hair becomes stronger and healthier, less breakage and less falling hair in the shower!! I have super fine hair and waiting for new hair to grow, I'm excited! Finally a product that really delivers!!! One new happy customer here. Just purchased again, this time bought the twin pack!

      Iman Bacha

      This product definitely works! Takes a bit of time but it does it’s job and best of all natural ingredients !

      Good for scalp health.

      Seems to prevent hair thinning but I am not sure about regrowth after 2 month.

      So far so good!

      Purchased this product as my hair started thinning and falling out and my scalp was also tender. I have been using it for several weeks now and have a seen a huge difference in the strength, volume and healthiness of my hair and scalp. Very happy!

      I'm going to keep going

      I have had a lot of hair loss due to iron deficiency. I'm taking vitamins and have started using hair hack. i think I can see some growth but I'm not really sure yet but I am still going to continue with it, I'm really hoping it works.
