Fine Hair Needs Growth Support Without the Weight
Fine hair is not fragile by nature — but it is unforgiving of the wrong routine. Heavy oils, rich conditioners, and dense treatments designed for thicker textures can weigh fine strands down, flatten volume, and create buildup that disrupts the scalp environment where growth begins. The result is hair that looks thinner, feels limp, and breaks before it can accumulate length.Fine hair needs growth support as much as any other texture. It just needs it delivered differently.As a licensed cosmetologist with 14 years behind the chair, 'Koriem founder Sarah Lewis... Read more...
Stop Losing the Length You Worked to Grow
Hair growth is happening in your scalp right now. The question is not whether your hair is growing — it almost certainly is. The question is whether you are keeping it.Length retention is the part of the growth conversation that most routines miss entirely. You can have a healthy, active scalp and still see no visible progress if your ends are breaking faster than your roots are producing. This is not a growth problem. It is a retention problem — and it requires a different solution.After 14 years behind the... Read more...
Consistency Is a Growth Strategy
The most common question in hair growth is: which product works best? The more useful question is: which routine will you actually repeat?Products matter. Formulation matters. But one of the most powerful drivers of visible hair-growth progress is how consistently you follow the ritual. A good routine performed irregularly will almost always underperform a simpler routine performed without interruption.This is not motivational advice. It is how the hair growth cycle works.As a licensed cosmetologist with 14 years behind the chair, 'Koriem founder Sarah Lewis built every 'Koriem system around this... Read more...
The 90-Day Ritual: Building a Hair Wellness Routine That Lasts
Hair wellness isn't a quick fix — it's a practice. The 90-day ritual is the minimum window to see meaningful, lasting change in your hair's condition.Why 90 Days?The hair growth cycle means that changes at the follicle level take time to become visible at the strand level. New growth from a nourished scalp won't appear overnight. Most customers begin to notice a difference in scalp feel and strand resilience within 4–6 weeks, with more visible changes in density and texture emerging at the 90-day mark with consistent use.What Consistency Actually...

Beauty From Within: How Internal Nutrition Supports Hair Health
Hair is built from within. Topical care supports the scalp and protects the strand, while consistent beauty nutrition supplies another layer of support for stronger, fuller-looking growth. That is why 'Koriem pairs outside care with inside-out support instead of treating either one as the complete answer.As a licensed cosmetologist with 14 years behind the chair, 'Koriem founder Sarah Lewis built the inside-out approach around this reality: support the scalp from the outside, and the follicle from within.Why Topical Products Alone Are Not EnoughScalp oils, shampoos, and conditioners work on the...

Wash-Day & Strand Care: Building a Routine That Actually Works
Wash day is the most important ritual in your hair-growth routine. It is the moment you cleanse the scalp, restore moisture to the strand, and set the conditions for healthy growth in the week ahead. Done consistently and correctly, it compounds over time. Done carelessly, it undoes what your other products are building.As a licensed cosmetologist with 14 years behind the chair, 'Koriem founder Sarah Lewis designed the wash-day ritual around one principle: protect what grows, so length can be retained.Pre-Wash: Prepare the Scalp Before You CleanseThe pre-wash step is...

Scalp + Hair Science: The Foundation of Healthy Hair
Your scalp and your hair strands are not the same thing — and treating them as if they are is one of the most common reasons growth stalls. The scalp is living skin. The strand is a dead fiber. What nourishes one does not automatically protect the other, and confusing the two leads to routines that address symptoms without ever reaching the source.As a licensed cosmetologist with 14 years behind the chair, 'Koriem founder Sarah Lewis built the 'Koriem approach around this distinction: support the scalp where growth originates, then...

Understanding Hair Changes: Shedding vs. Breakage and the Hair Growth Cycle
Not all hair loss is the same — and knowing the difference changes everything about how you care for your hair.Shedding vs. BreakageShedding is a natural part of the hair growth cycle. Losing 50–100 strands per day is normal. Shed hairs have a white bulb at the root — they've completed their cycle. Breakage, on the other hand, happens mid-strand. No bulb, jagged ends, and often a sign of structural damage from heat, tension, dryness, or chemical stress.The Four Phases of the Hair CycleAnagen (Growth): The active growth phase, lasting...
