For some time now, a new hair care technique has been causing a sensation: “Reverse Shampoo”.
But what exactly is it? And why should you adopt it? 


Julie Pernet, our doctor of pharmacy and certified trichologist, has looked into this innovative method in order to offer you an in-depth analysis. She reveals the promises of this technique for healthier hair.

 

 

What is Reverse Shampoo?

 

 

The concept of reverse shampoo consists of reversing the usual order of washing hair by first applying care before shampooing. Unlike the traditional method where we start by washing the hair with shampoo followed by the application of the treatment, the reverse shampoo promotes the idea that this new washing sequence can provide additional benefits both for the scalp and for the lengths.

The benefits of Reverse Shampoo: .................................................. .................................................. ......

1. For the scalp 

 

The Reverse Shampoo offers significant benefits for the scalp, particularly in terms of protection and regulation.

 

This method helps regulate sebum production by maintaining optimal water balance. Indeed, the emollient agents in the pre-shampoo treatment prevent excessive dryness, while the cleansing agents in the shampoo eliminate impurities, excess sebum and product residue without stripping the scalp of its natural essential oils.

 

By forming a protective barrier, pre-shampoo treatment can also minimize damage caused by shampoo's surfactants, which can sometimes be too strong for sensitive scalps or damaged hair.

 

The risks to the scalp of shampooing alone without prior care include:

 

  • Disruption of sebum production : Excessive washing or the use of shampoos that are too harsh can stimulate excessive sebum production, leading to an oily scalp, or conversely, cause increased dryness.

 

  • Irritation and sensitivity : Harsh chemicals in some shampoos can irritate the scalp, causing itching, redness, or allergic reactions, especially if the scalp is sensitive.

 

  • Alteration of the hydrolipid barrier : Frequent use of shampoos without prior protection can damage the natural protective barrier of the scalp, increasing vulnerability to external aggressions.

 

Using a pre-shampoo treatment is therefore a key step to protect the health of the scalp, especially if the scalp is prone to dryness, sensitivity or sebum imbalances.

2. For lengths

 

This technique also provides remarkable benefits for the length of the hair. 

 

By applying the pre-shampoo mask first, the cationic agents it contains form a protective barrier on the hair cuticle, reducing potential damage caused by shampoo, such as drying out if formulated with sulfates or other strong cleaning agents.

 

In addition, the initial application of the pre-shampoo treatment creates an environment conducive to the nutrition and hydration of the hair, maintaining a better balance of natural oils on the lengths and ends, thus strengthening internal bonds and smoothing the cuticle . This combined action deeply nourishes the hair, making it softer, smoother and shinier after washing.

 

 

 

Reverse Shampoo Protocol: 

 

To put Reverse Shampoo into practice, here is a standard protocol to follow:


Step 1 – Feed:
Start by applying a nourishing treatment such as hair whipped cream, emphasizing lengths and ends. Leave on according to product directions for deep hydration.


Step 2 – Process:
Then apply a treatment mask specific to your hair needs, distributing it evenly over the scalp. Leave on to allow the active ingredients to revitalize and strengthen the scalp.

 

Step 3 - Wash: 
After letting the treatments act, wash your hair gently with a pH 5 shampoo. Gently massage the scalp and roots, then rinse thoroughly with lukewarm water.

 

Step 4 - Seal:
Complete the process by generously applying a conditioner on the hair, making sure to cover all the strands. Leave on for a few moments, then rinse thoroughly to seal in moisture and add shine to the hair.
