From root to tip

Hair growth takes place within the follicles and a healthy scalp equals beautiful hair. That’s why our approach has always been scalp first.

By restoring the health of your scalp to create the ideal conditions for hair gain, Harklinikken’s Extract is created for use in tandem with our product line to protect your scalp from problematic ingredients and external irritants that diminish hair quality and growth and make existing hair strong and long.

Our entire range of products is based on naturally derived, pure and safe ingredients.

Online Hair Assessment

Exploring your hair's true potential

The Extract is carefully hand-blended to individual requirements, including scalp condition and hair thinning patterns. Even lifestyle factors and genetics are taken into consideration. This is why we ask you to take our online Hair Assessment to evaluate your hair and scalp before creating an Extract that is unique to you.

We accept only those we believe can achieve the hair improvement they are looking for onto our regime, which is why our online Hair Assessment is a great place to start. It is available 24/7 and will give you an immediate answer as to whether or not you are a suitable candidate for hair improvement. 

Your Extract journey starts with a consultation

1. Consultation and formulation

Before you can begin achieving fuller, healthier hair, we evaluate the current condition of your hair and scalp to determine whether you are a suitable candidate for our Extract. Once accepted, we then custom hand-blend a formula that is unique to you.

2. Daily application

Your personal Extract must be applied to your scalp twice daily, 30 minutes apart. The simple, effective and quick treatment easily integrates into your daily self-care routine – just like brushing your teeth or cleansing your face.

3. Improvement and reformulation

We continuously evaluate your progress, documenting your hair growth while adjusting your Extract to the changing response and needs of your hair and scalp.

Takes some getting used to

I think I notice changes, it’s been 6 weeks, want to give it a full 3 months before I really decide. Getting used to washing my hair more frequently is an adjustment, but the shampoo and conditioner are great and the hydrating lotion is wonderful. I feel like the volume is increasing and I have more luster. I do recommend the extract at night as it does make my hair a bit “dirty” looking, and takes a minute to absorb. I am currently washing every other day and it’s manageable.


This product Works!!!!
You must be patient.
I highly recommend this.

Hair Rebirth

Thus far it has been a very positive one. Since I began using this product on August 15 2023, I have noticed significant changes in my follicles and hair regrowth. I was very fortunate to have been referred to this hair clinic. I will continue to use it as long as I need.


It’s only been two months and I could literally weep for joy!!! My hair is thicker and healthier! I still have a ways to go but to see this much progress this soon is astounding!
