Why Silicones and Sulphates are Bad for Your Hair?

Pourquoi les silicones et les sulfates sont-ils mauvais pour vos cheveux ?

Que sont les sulfates ?

Les sulfates sont ajoutés aux produits nettoyants pour les faire mousser. Non seulement ils moussent, mais ils se combinent également à l'eau pour émulsionner les graisses, les dispersant dans l'eau et les éliminant ainsi. On les appelle tensioactifs anioniques. Ils sont essentiellement ajoutés aux produits capillaires pour éliminer les impuretés. Un shampoing classique contient 15 % de sulfates. Bien que les shampoings à base de sulfates nettoient efficacement les cheveux, ils peuvent également les priver de leurs huiles essentielles et irriter la peau. Si les sulfates sont utilisés dans les shampoings et après-shampoings traditionnels, c'est parce qu'ils sont économiques et efficaces. Les cheveux lisses étant la norme et peu sensibles aux effets desséchants des sulfates, les marques grand public n'ont pas eu besoin d'utiliser des ingrédients plus doux (mais plus coûteux).

Pourquoi les sulfates sont-ils mauvais pour vos cheveux ?

Le problème des cheveux bouclés est qu'ils ont tendance à être plus secs. En effet, le sébum produit par le cuir chevelu ne pénètre pas aussi facilement dans les boucles que dans les cheveux lisses. Les shampoings sans sulfates, qui éliminent les huiles naturelles des cheveux bouclés, peuvent donc les assécher davantage, les abîmer et les casser. Cela peut également poser problème sur les cheveux colorés, car les sulfates peuvent également les décolorer.

Que devriez-vous utiliser à la place des sulfates ?

Les tensioactifs cationiques ou non ioniques constituent une alternative aux tensioactifs anioniques, plus doux pour tous les types de cheveux. Au lieu d'acheter des shampoings contenant des sulfates, vous pouvez opter pour des shampoings sans sulfate, des shampoings sans savon ou même des argiles comme l'argile verte, aux excellentes propriétés nettoyantes. Ces produits, sans sulfates, ont donc un pouvoir moussant moindre, ce qui ne les empêche pas de nettoyer les cheveux. Pour beaucoup, ce n'est pas ce à quoi ils sont habitués, mais il existe de nombreuses alternatives intéressantes, comme nos shampoings Custom Blend. Tous nos shampooings Sans sulfate, ils offrent un excellent pouvoir moussant et laissent vos cheveux propres et frais. Vous pouvez choisissez vos propres ingrédients aussi et mettez votre nom sur la bouteille pour montrer que c'est juste pour vous.

Que sont les silicones ?

Les silicones sont souvent utilisés dans les après-shampoings et les produits coiffants pour donner aux cheveux la souplesse nécessaire au démêlage et leur apporter plus de brillance. Ils sont également utilisés comme protecteurs thermiques. La plupart des silicones se terminent par un cône, ce qui les rend faciles à repérer au dos d'une étiquette. Les silicones sont un type de polymère qui recouvre les cheveux d'une fine couche hydrophobe (imperméable). Ce revêtement réduit la porosité des cheveux et limite ainsi la perte d'hydratation, ce qui réduit l'apparence des frisottis.

Pourquoi les silicones sont-ils mauvais pour vos cheveux ?

Le problème avec les silicones, c'est qu'ils forment un film autour des cheveux, empêchant l'hydratation de pénétrer dans la cuticule. Ce film attire également les impuretés et favorise l'accumulation de produits capillaires, nécessitant des lavages plus fréquents. Cependant, comme les silicones sont résistants à l'eau, il faut les laver avec un shampoing puissant pour éliminer le produit. Ce cycle de lavage agressif et d'accumulation de produits rend les cheveux secs et cassants, car ils ne sont pas réellement hydratés.

Que devriez-vous utiliser à la place des silicones ?

Bien que certains silicones soient moins résistants à l'eau que d'autres, je recommande d'opter pour des après-shampoings sans silicone. Ceux-ci utilisent généralement des huiles plutôt que des polymères pour enrober et hydrater les cheveux. Certains produits utilisent des esters de silicone, similaires aux silicones traditionnels, mais qui accumulent moins de produit. Ils sont plus nécessaires dans les produits thermoprotecteurs, car les huiles peuvent brûler les cheveux. Chez That Good Hair, notre produits capillaires sur mesure autoriser sont tous 100% sans silicone et utilisez plutôt des hydratants et des huiles naturelles telles que Glycérine et le laurate d'isoamyle.
Silicones non solubles dans l'eau à éviter se terminent généralement par « -icone ». Un symbole couramment utilisé dans les produits capillaires est Diméthicone
Les sulfates déshydratent les cheveux, tandis que les silicones empêchent l'hydratation de pénétrer et favorisent l'accumulation de produits. Ces deux substances sont néfastes pour les cheveux et, en termes de That Good Hair Produits capillaires personnalisés nous nous assurons que tous nos produits capillaires sont sans sulfate, sans silicone, sans parfum, sans parabène et plus encore.

Vous devez toujours être conscient de l’impact de vos produits sur vos cheveux et votre santé.

✨ Review: Hydrating Mist + Hair Oil Duo ✨ My son has been using the hydrating mist and hair oil from this company consistently in his hair routine, and the results honestly speak for themselves. His hair looks healthier, shinier, and has so much more volume now. On Eid especially, his hair looked amazing — soft, defined, and full without looking heavy. The hair oil has become his favourite part of the routine. He massages it into his scalp twice a week and leaves it in for a couple of hours before washing. It really helps keep his scalp moisturised and makes his hair feel stronger and smoother afterwards. The hydrating mist works perfectly alongside it because it adds lightweight moisture and shine without making the hair greasy. He usually sprays it before styling with mousse, and it helps define the hair while keeping frizz away all day. ✨ What we noticed after regular use: Shinier, healthier-looking hair Softer texture Better volume and definition Less dryness and frizz Hair feels hydrated but lightweight Overall, this combination has worked really well for his routine, especially for keeping his hair looking fresh and styled naturally. Definitely products we would keep using. ⭐

I have only just started using the products. It’s maybe just three weeks now but this leaves my hair feeling so clean without any white residue like some other cleansers. It’s a must have and because I feel so clean and all residue is removed. I no longer wash my locs I just use this now and it gives me the same effect pending when I decide to redo my locs at the salon.

Since using the hair butter and hydrating spray my daughter’s hair has been easier to style and there has been less tears. Before her hair was dry but after using the products her hair looks shiny and healthy. We love how they smell too. Would definitely recommend.

It absorbs beautifully without sitting greasy on top, which is rare. My hair drinks it up and just looks expensive afterwards. The frizz? Calm. The dryness? Gone. The ends? Sealed and behaving.

I RARELY write reviews so trust me when I say this product has my heart! I believe it's my fourth time purchasing it and honestly my hair absorbs and loves it. I find my hair to be frizz free and I barely get any breakage, I put that down to how moisturising it is. I also use it for my kids and their hair loves it too! I love how gentle the ingredients, it gives me a peace of mind

Customer photo review of Hydrating Hair Mist

I’ve been using this hydrating hair mist for a short while now, and I’m genuinely impressed with the results. My scalp feels well-hydrated and comfortable, without any dryness or irritation. My hair feels noticeably softer, healthier, and more manageable, with a natural shine that doesn’t feel greasy or heavy. What I really appreciate is how lightweight the mist is—it absorbs easily and refreshes my hair without weighing it down. It’s perfect for daily use, especially when my hair needs a quick boost of moisture. Overall, this product has helped improve the look and feel of my hair, leaving it nourished, refreshed, and well cared for. I would definitely recommend it to anyone looking to maintain hydrated, soft, and healthy hair.

I was recommended this by someone who works here for my 4 month old baby. I’d beg to differ.. essential oils and tea tree are definitely not recommended for a baby so young. I tried it on myself it’s ok but definitely won’t be buying from here again. I wanted to like it but it’s not for me

Moisture Cream Hair Butter

Customer photo review of Hydrating Hair Mist

I was approached in Westfield Shopping centre as I have curly hair and was told the product would be perfect for my type of hair. I have been looking for something that would be light enough not to weigh my hair down but give it the moisture it needs. I was super excited to use the mist but unfortunately it just dried my hair out. It was very light on my hair but didn’t enhance the curl pattern any more than what it was. I am very disappointed with the product especially for the price. I have to use it with my original hair product for it not to dry my hair out. I would not purchase again, Sorry 😕 I wanted to love it but it’s not for me!

Customer photo review of Satin Bonnet (Cream and Gold Reversible)

I love this bonnet! 1) I've become a restless sleeper so I toss and turn quite a bit and this does not come off. I don't have to do the mid sleep checks anymore to see if it's still on my head 2) I've spent so much money on silk bonnet and it just not living up to the hype but this £8.50 satin bonnet has done everything i thought those silk bonnets would do. I have thick wavy hair and these have been amazing controlling the frizz!

I Decided To Try The Mist After Using The Oil For A Year. It's Great For When My Hair Is Styled; It Was Especially Good When I Was On Holiday In Ghana; My Locs Were Hydrated and When I Took Them Out Of The Style, They Were Moisured With No Need For Oil. I Only Need To Use It Once A Week In The UK; About Every Other Day In Hot Weather. Give It A Try; The Larger Bottle Is Great Value.

After doing the big chop I was so worried my hair wouldn’t grow back quickly but omg.. after using this hair oil (along with other TGH products) I finally feel like I have my crown back. I swear by this hair oil!! The scent, the texture and the way my hair has grown back so healthily! I even use it on my hair clients. I can’t fault it at all, thank you ThatGoodHair!! ❤️
