Review: Good - Good product
Review: First Impressions After Use - I have started using RULE Cosmeceuticals Stem Cell Hair Growth Serum #4. My review is in the early stages of using the product (and my first experience with this brand.) First impressions. If you’re a young brand entering the premium hair and skincare market, you better bring some good branding. Mission accomplished. The serum is beautifully presented in a black box, with embossed printing inside. The matte black bottle is also nice with a unique push button dropper top. The serum is non-greasy. It is fragranced. It smells like alcohol and sandalwood to me. The scent leans masculine, but not overtly so. The amount of fragrance is noticeable, but not cloying. If you don’t like synthetic fragrance whatsoever, this might not be for you. I applied to my scalp at night. As directed, a few drops on the scalp areas (with clean, dry hair.) Not greasy and one application does not weigh my hair down. The ingredient stack in this product indicate that it is stimulating. I could feel a very subtle warmth (def not a burning type reaction.) I intend to keep using it at night. Something that confused me is how the product listing says to use a dropper a week, but the actual bottle says daily AM or PM. I think they mean to use a few drops daily, which adds up to one dropper full per week. At this point, I rate it as very good — 4 stars. It will take time before I will see changes in my hair.

### ⭐⭐⭐ Looks and feels good but didn’t have the desired effect for me
*by D***E on May 14, 2025*

This hair growth product was packaged and presented well. Unfortunately, I did not get any benefit from using this product. No hair growth was observed.
