Plastic Free Curly Girl method

The curly girl method can be completely plastic free thanks to By Selina Products. I have invested in all of the products and my hair has never been happier and curlier.

As a small business Selina adds a LOVELY personal touch to her deliveries, and the release of the defining curl gel has been a revelation for my curly wurly world.

I cannot recommend her products and plastic free ethos enough, and if you have curly or wavy hair and a conscience- her products are for you!


I was so happy to receive my BY SELINA Defining Curl Gel recently. The new formula is amazing and my curls are really defined yet super soft. The gel arrived promptly and was packaged beautifully. I especially liked the little personal note included. I will definitely be purchasing again in the future and would highly recommend this product to other curlies.
