An Expert Explains Why Your Conditioner Isn’t Working

Today our hair care has become more and more demanding. The reason? We have greater access to information and more options, which allows us to find the specific products and treatments that best meet our needs. However, there is still a lot to learn, and if you also feel that your conditioner has stopped working, the cosmetologist Héctor Núñez (better known as Cosmetocrítico) is clear: “It’s not the same to have hair that is young and lightly damaged as hair with a history of intense wear and many questionable decisions.”

As he explains, not all of us should use shampoo, conditioner, and hair mask. In fact, it is our mane that sets the baseline. “Brands, by creating complete lines with shampoo, conditioner, and hair mask, have managed to implant in our heads the idea that we have to use it all. But that isn’t true.”

The reason? The conditioner and the hair mask do not perform exactly the same function. “Conditioners contain conditioning agents and a lighter oily phase, while hair masks incorporate a greater lipid load, emollient ingredients, and more intensive formulas.”

Therefore, “the choice should not be made by marketing or habit, but by real need.” When is it better to use conditioner? When your hair has not suffered too much from bleaching or heat tools. When is it better to use a hair mask? When your hair has a history. That said, whatever you choose, “they should always be applied from mid-length to the ends. The scalp is not very fond of it; for the scalp, the main protagonist remains the shampoo.”

The Best-Recommended Conditioners


Revita CBD® Conditioner.

Revita CBD® Conditioner. I like it because it features a broad-spectrum CBD formula and it is a perfect conditioner to use as an anti-hair-loss treatment, as it acts as a follicle stimulant with antioxidant and anti-inflammatory properties for all hair types.


La Biosthétique Structure Repair Nourishing Conditioning Spray.

The Biosthétique Structure Repair Nourishing Conditioning Spray. It nourishes instantly without weighing hair down. Its oily-based formula helps repair the hair fiber and improve texture from the first application. You will feel hair softer, more manageable, and visibly healthier.


Gisou Honey Infused Conditioner.

Gisou Honey Infused Conditioner. Nutritive and lightweight, it is enriched with Mirsalehi Honey from the Mirsalehi Bee Garden, formulated to detangle and revitalize the hair effectively and gently, achieving hydrated, manageable, and strong hair.


Acondicionador Deep Care reparador de Teknia.

Teknia Deep Care Repair Conditioner. Rebuilds, strengthens, and increases resilience with an extra hydration. You can achieve up to 35% more hair resilience, conditioning, and strengthening from within the hair. Best of all, you can use it daily because it is so effective (yet lightweight) that it does not weigh hair down.


Aveda Botanical Repair Conditioner.

Aveda Botanical Repair Conditioner hydrates and detangles instantly to prevent breakage. It strengthens and repairs thanks to its new technology derived from the energy of plants, while at the same time it creates bridges at the heart of the hair to strengthen it from within and hydrate it lightly without weighing it down.
