Hello there! š
This is finally the last chapter of the “Recognizing a good Shampoo” topic.
After the basics of shampoo surfactants in the part 1 and part 2Ā and in the last post (which you can find here) I talked about the most common “extra ingredients”.
I know I haven’t covered all the possible things but I did what I could š
Theory: Recognizing a Good Shampoo (Part 4 ā Useful Actives)
Hello Hello! :D To finish our journey through the shampoo bottle, we are looking at the “useful” ingredientsāthe actives that theoretically make a difference for your scalp and hair.
However, we must be realistic: a shampoo stays on your head for maybe a minute before itās rinsed off. While these ingredients are great, they are often used at minimal amounts just to look good on the label. š Here is what to look for!
1. The “Label Stars”: Vitamins & Hydrators
-
Panthenol (Vitamin B5): This is a famous one! Itās a humectant that helps hair retain water and creates a protective film. While itās a great ingredient, donāt expect miracles from a shampoo alone since it barely has time to sink in.
-
Tocopheryl Acetate (Vitamin E): A good antioxidant, but again, its effect in a wash-off product like shampoo is debatable. Itās often there more for “poetry” than performance! :D
-
Aloe Barbadensis: We hear so much about Aloe! Itās hydrating and soothing. Note: Some people are actually allergic to Aloe, so if you notice an itchy scalp after switching to an “Aloe shampoo,” that might be why!
2. Scalp Specialists: Dandruff & Oil
If you have a problematic scalp, look for these near the end of the INCI (usually used at ~1%):
-
Piroctone Olamine: A very effective ingredient for fighting dandruff.
-
Salicylic Acid: Often combined with Piroctone Olamine to help clear the scalp.
3. The “Energy” Boosters: Hair Growth Extracts
Take these with a pinch of salt! Hair loss is often genetic, and no shampoo is a “miracle cure.” However, these ingredients aim to improve scalp oxygenation and blood circulation:
-
Caffeine: Helps stimulate circulation in the scalp.
-
Arginine & Lysine: Amino acids that help repair hair and are thought to support growth.
-
Plant Extracts: Look for Ginkgo Biloba, Hops, Mallow, or Pumpkin Seed extract. They give the skin a little “energy,” but they aren’t magic!
4. My Favorite: Betaine (Trimethylglycine)
You know I love this one! :D Remember: this is NOT the surfactant (Cocamidopropyl Betaine). This is a humectant that makes detergents much milder.Pro Tip: If you find this ingredient near the beginning of the INCI (around 5%), you are almost certainly looking at a high-quality, mild shampoo.
Final Summary Table: Actives at a Glance
| Ingredient | Primary Goal | Reality Check |
| Piroctone Olamine | Anti-Dandruff | Effective at ~1% |
| Caffeine / Arginine | Scalp Stimulation | May help, but not a “cure” |
| Panthenol | Hydration / Film | Good, but mostly marketing in shampoo |
| Trimethylglycine | Mildness | Great sign if high in the list! |
That is it for our shampoo series! I hope you now feel like you have all the tools you need to choose the best product for your specific hair and scalp.
