Reviews

Textura ușoară, curata parul bine

"Textura ușoară, curata parul bine dar cu blândețe. Parul meu este ușor deteriorat, acest sampon curata parul dar nu il usucă. Mie personal imi place foarte mult il folosesc de ceva vreme si nu vreau sa il schimb."

— Eleonora D. (5/5)

Great product!

"One of the best shampoos I've ever used. My hair was looking dry and weak, and after the first usage, I already saw a lot of difference. It has been a few weeks using it, and I'm alternating with the orange shampoo too, they both pair up really well, and my curls are loving it!"

— Izabelle (5/5)

Really loving my new products!

!!

"Funktioniert! Meine Haare sind so viel kringeliger, sobald ich das Treatment hier nutze. Der Geruch ist außerdem unfassbar angenehm so wie alle anderen Curlsmith Produkte. Was mir besonders im Vergleich zu anderen Marken heraus sticht ist der Slip. Einmal aufgetragen, gleiten meine Hände durch die Haare und das detangling tut auch nicht weh!"

Q&A

Is this color safe?
Hi Hillary, Thanks for reaching out to us. The Core Strength Shampoo from Curlsmith is generally safe for color-treated hair. It is formulated with nourishing ingredients like proteins and moisture-rich compounds that help strengthen and maintain hair health, which can be beneficial for colored hair. However, it’s always a good idea to check the ingredient list if you have concerns about specific sensitivities, as some proteins can sometimes make color-treated hair feel stiff if used in excess. If you have further questions. Please reach out to us at hello@curlsmith.com and our team will be able to help you. Thanks, Curlsmith
I have low porosity hair, can I use the core shampoo and the multi-tasking conditioner on the same wash day or would that be too much protein ? I’m looking for a mild protein treatment that I can use to replace my old one (it contained silicones).
These contain low protein properties so can be used together and regularly without risk of protein overload!
Will this work for my dry brittle low porosity hair? My hairs been fragile lately and suffering from breakage and I'm not sure why.
Hi, Giselle. The Core-strenght shampoo is greattle for brittle hair. If you are seeking moisture, you might want to check out the essential moisture cleanser.
I wash my hair twice a week, and I currently use the bond curl rehab salve followed by double cream deep quencher once a week. The protein from the bond salve has done WONDERFUL things so far, and I'm wondering if I should use the core strength shampoo on the other was days? I don’t want to do a protein overload and don’t really know how much protein is too much.
Hi, Lauren, Yes, you can! Our products except for the bond salve have minimal amount of protein and won't cause protien overload!
I need this is a travel size please! xxx
Hi Jo, Thank you for your interest in the Core Strength Shampoo! Currently, we don't offer it in a travel size, but we truly appreciate your feedback and will consider this option for the future. If you have additional questions. Please reach out to us at hello@curlsmith.com and our team will be able to help you. Thanks, Curlsmith
I feel like the core strength shampoo leaves the top of my hair oily after I use it. Is that normal?
Hi! We would advise to try leaving longer between wash days
Is this formula color safe?
Yes it is!
Can u use this in newly coloured hair

What is the PH level of this shampoo?
We have designed all our products to be gentle on the scalp and safe for everyday use, so we made our products with a ph of 5 to cater to all different scalp needs.
I have a lot of hair loss. Will this formula of shampoo help with the shedding or another recommendation ?
This will not repair hair loss / hair shedding but will help to strengthen and repair damaged hair
